Vehicle was running fine.
One day, wife turns on headlamps and horn starts blaring.
Shuts lights off, horn stops.
This is consistent and repeatable.
Went to start it next day and battery is completely dead.
Hooked up jumper cables and got lots of sparks.
Let it charge up a minute and had her turn the key.
Rav started right up.
As soon as I removed jumper cables, the Rav died.
I re-connected cables (again lots of sparks) and the engine started cranking itself – without the key inserted.
Again, this is consistent and repeatable.
There are no blown fuses and the relays seem fine, but I haven’t replaced any.

I have access to an automotive probe and a basic understanding of automotive electrical, but don’t know where to start in this case.



Sounds like the starter relay/solenoid is sticking a bit. Also the Battery is not being charged. The alternator is not charging the battery and or the battery itself is no longer able to take a charge. That is why the engine dies as soon as the jumper cables were removed.

If the battery is around 4 years old or older it would be a good idea to replace it anyway. Once the battery is replaced then you can perform further testing.

You can tap on the starter relay/solenoid with the end of a screw driver and it may cause it to release.

Check all fuses and Fusible links. Here is a wiring diagram for reference.

I have retrieved code 44 from OD flashlight, which points to an issue with the “transmission rear output shaft speed sensor”. The car has A540H transmission. Where is this speed sensor located? How many speed sensors does this transmission have?



This vehicle has two Speed Sensors. The Front Speed Sensor and the Rear Speed Sensor. The No. 1 Vehicle Speed Sensor is located on top of the transaxle. The No. 2 Speed Sensor is Located at the rear of the transaxle.

The front speed sensor detects vehicle speed based on ring gear RPM. The Rear speed sensor detects rear wheel speed based on transfer drive gear RPM. I have provided testing procedures for both sensors.

Testing the No. 1 Vehicle Speed Sensor (VSS)

1997-toyota-rav4-vss-location-diagram

  1. Disconnect electrical connector from No. 1 VSS, located on top of the transaxle. See Figure. Connect positive battery lead to terminal No. 1 and negative to terminal No. 2. Connect positive lead of voltmeter to terminal No. 3 and negative to terminal No. 2. See Fig 1.
  2. Raise and support one vehicle front wheel. Rotate wheel and monitor voltmeter. Ensure voltage changes from zero to 11 volts. Voltage should change 4 times per each revolution of speed sensor shaft. Replace speed sensor if voltage does not change as specified.

1997-toyota-rav4-vss-test-diagram

Testing the No. 2 Vehicle Speed Sensor (VSS)

  1. Ensure ignition is off. Access ECT ECU. See Figure Above for location. Backprobing ECT ECU harness connector with ohmmeter, measure resistance between terminal RR+ and terminal RR-. See Figure below. Resistance should be 560-680 ohms. If resistance is within specification, replace ECT ECU. If resistance is not within specification, go to next step.
  2. Remove rear speed sensor from transaxle. Measure resistance between sensor terminals. Resistance should be 560-680 ohms. If resistance is not specified, replace sensor. If resistance is specified, check and repair circuits between sensor and ECT ECU.
  3. Check voltage between sensor terminals when a magnet is put close to tip of sensor. If a low intermittent voltage is generated, sensor is okay. If no voltage is generated, replace speed sensor.

2012 Toyota Camry

I bought a 2012 Toyota Camry ELE repaired after a collision. The SRS light stays on. I have safely unplugged and checked the SRS connection under the passenger seat. I sent the SRS ECU to be reset and then re-installed it. The SRS light is still on. There are no OBD2 codes. What to do next?



If you have a scan tool you may connect it and pull the codes or do it without a scan tool. I have provided the procedures below for both scanning and clearing the present codes. I have also provided a list of corresponding diagnostic trouble codes.  Then check wiring and sensors that correspond to the present code or fault. These codes would begin with a B.

Scan Codes without a Scan Tool

  1. Turn ignition switch to Acc or On position.
  2. Wait approximately 20 seconds.
  3. Connect DLC terminal Tc and E1 or Tc and CG with special diagnosis check wire tool No. 09843-18020 or equivalent jumper wire.
  4. Read two-digit DTC from SRS warning lamp as blinks as follows:
    a. If lamp flashes two times per second, there are no DTCs stored.
    b. If a fault code is indicated, first digit will flash, then after 1.5 seconds elapse, second digit will flash.
    c. If more than one code is stored, 2.5 seconds will elapse, then second code will appear.
    d. DTC flashes will be displayed from smallest numerically to largest.
    e. After all stored DTCs have been read, 4.0 seconds will elapse and DTCs will be repeated.
Clearing Diagnostic Trouble Codes without a Scan Tool
  1. Connect two special diagnosis check wire tools No. 09843-18020 or equivalent jumper wires, to DLC terminals Tc and AB or Tc and CG.
  2. Turn ignition switch to Acc or On position and wait approximately six seconds.
  3. Alternately ground each jumper wire twice in one second cycles as follows:
    a. Ground Tc jumper for .5-1.5 second.
    b. Release Tc ground and immediately ground AB jumper within .2 second.
    c. Ground AB jumper for .5-1.5 second.
    d. Release AB ground and immediately ground Tc jumper within .2 second.
    e. Ground Tc jumper for .5-1.5 second.
    f. Release Tc ground and immediately ground AB jumper within .2 second.
    g. Ground AB jumper for .5-1.5 second.
    h. Release AB ground and immediately ground Tc jumper within .2 second.
  4.  Ground Tc jumper.
  5. SRS warning lamp will blink in a 50 milli-second cycle several seconds after clearing procedure is completed to indicate DTCs have been cleared.

I have a new suspension set from a 2019 Hilux. Can fit on my old 2001 model?



No. The part numbers are completely different and so is the design. With that being said you could make them fit with a set of cutting torches, a welder and a little fabricating.

My engine dies on low speed (in hold ups)when the AC is on. I ve already clean the throttle and oxygen sensor, cannot accertain fuel pump pressure, but the car works fine if the AC compressor not ON.



Idle speed can be adjusted but the use of a scan tool is required. One thing to check before you get into that would be to check the PCV Hose connections and condition. Check the the connections and hose for leaks. There is a chance that a Code P0505 – idle control system, may be set in this condition. Check the PCV hose and intake for leaks if code P0505 is set.

Idle Speed Adjustments

Curb Idle Speed

  1. Ensure engine is at operating temperature.
  2. Connect scan tool to DLC.
  3. Turn power switch to ON.
  4. Turn scan tool ON.
  5. Follow scan tool manufacturers instructions.
  6. Idle Speed: 600-700 RPM.

I replaced the fan clutch this past January because it would squeal really bad for a short while when starting the engine. Now it’s doing it again. Will pulling it apart and adding silicone oil likely fix it, or did I just get a poor after market part, and I need to replace it again?

Basically, my question is can being low on silicon oil cause a fan clutch to squeal? In which case it may be worth trying adding more oil before replacing again.





In most cases the squealing noise is coming from failing serpentine belt. I created the video below to help assist in such an occasion. If you are certain the fan is at fault it doesn’t cost you anything but time to try something before replacing a part. But in my experience if there is a leak, unless you fix the leak, it will still leak.

How to Check your squealing belt

 

How to Replace Clutch Fan

Removal & Installation

  1. Before servicing the vehicle, refer to the precautions.
  2. Disconnect the negative battery cable.
  3. Remove the engine undercover.
  4. Drain the cooling system.
  5. Remove the 2 bolts and the air pipe, as necessary.
  6. Remove the upper radiator hose from the radiator.
  7. Remove the oil dipstick guide, by removing the bolt.
  8. Remove the power steering drive belt, by loosening the lock bolt and adjusting bolt to the idler pulley, if equipped with power steering.
  9. Remove the No. 2 fan shroud, by removing the 2 clips.
  10. Remove the No. 1 fan shroud, by removing the 4 bolts.
  11. Loosen the idler pulley nut and adjusting bolt and remove the air conditioning drive belt, if equipped with air conditioning.
  12. Remove the alternator drive belt, fan (with fan clutch), water pump pulley and the fan shroud.

◦Stretch the belt and loosen the water pump pulley mounting nuts.

◦Loosen the lock, pivot and the adjusting bolts for the alternator.

◦Remove the alternator drive belt.

◦Remove the 4 water pump pulley mounting nuts.

◦Remove the fan (with fan clutch) and the water pump pulley.

To install:

  1. Installation is the reverse of removal.
  2. Tighten the fan nuts to 16 ft. lbs. (21 Nm).
  3. Fill and bleed the cooling system.
  4. Start the engine and check for leaks.

So I’m in the process of fixing my power steering… My mechanic in laws said to replace the pump but every time I put fluid in there it works for a week or so and then the reservoir is empty so I was thinking maybe a leak.. My Question is Would I be better off replacing the whole pump or do I only need to do something else?



You need to locate the leak and repair it. Then fill it with fluid. The power steering is a closed system and should not loose fluid ever. Replace the pump if that is what is leaking.

Power Steering Pump, Replace

  1. Remove righthand front fender apron seal.
  2. Raise and support vehicle, then remove righthand front wheel.
  3. Remove clamp plates and holders, then the clamp from tube.2004-toyota-avalon-power-steering-pump-diagram
  4. Loosen drive belt adjustment bolt, then remove drive belt.
  5. Disconnect oil pressure switch connector.
  6. Remove power steering pump mounting bolts, then the pump with pressure tube attached.
  7. Remove oil pressure switch from union bolt.
  8. Remove union bolt and gasket.
  9. Reverse procedure to install, noting the following:

a. Torque wheel lug nuts to 76 ft. lbs.

b. Torque power steering pump mounting bolts to 32 ft. lbs.

c. Torque power steering pump pressure tubes to 33 ft. lbs.

Gauge fuse keeps blowing 2001 Toyota 4Runner Limited V6

1999 Toyota 4Runner

The beginning of November my 4runner broke down. We changed the alternator. Well ever since my . Extremely fast almost to the point, you can’t even drive around in it for 10 minutes without it blowing again.

The end of Nov. it went dead on me. So we got a new battery. Once the new battery was in we noticed how the lights inside and out would go real dim when I wasn’t on the gas pedal but as soon as I would push the gas it would brighten back up. Also the same with the air(it’s cold so it’s heat atm). Also, when my alternator went out the first time the gauges and the air cut off, the fuse blew but I didn’t know that at the time.

I’m at a loss on what to do anymore with it. I’ve read everything from a short to the ac compressor but I don’t know what could be wrong. My husband has been trying to fix on it and look things up but he also isn’t a mechanic. But he can normally figure out what’s wrong but we are stuck. Please help. I don’t want to get rid of it but if I have to I will.



Gauge fuse keeps blowing

Looking at the wiring diagram in reference to the alternator and gauges I see a DIODE between the IGN fuse and the alternator. If anyone of the wires in the wiring harness are shorted or the diode has failed it may cause this issue. Checking the wiring in the wiring harness would be a good first step.

Unplug the connectors and check for continuity from the blown 10 amp Gauge fuse to ground. Then Isolate the connections and test the wires to each other to find the short.

How to Use a Multimeter

It may be internal in the alternator. I will just say that if you have replaced it with a REMANUFACTURED(REMAN) alternator there is a good chance the alternator is bad again.

Toyota Camry

I have 2007 Camry, it is making knocking sound when I go over 80Kmph(50mph) from the right front side. No sound while turning, only when driving straight at high speed. What could be possible problem?



I would guess an air damn/splash shield or piece of trim has come loose. Damage can occur easily if driven over a parking block, etc. Make sure to check the Right Front Fender Splash Shield and Wheel Opening Extension Pad.
