Do you have any knowledge or expertise in OBD2 and the use of code reader\/scanners ? I\u2019ve written some 5 or 6 other guys so far on my problem, only one has replied, could not help much. Anyway, here goes —–
I have a 2009 Ford Escape XLT, 2.5 engine, with a Type \u2018A\u2019, ISO 15765-4 Data Link Connector, with the following pins —-
Pin 3 —- Module Communications Network A Pin 4 —- Chassis Ground Pin 5 —- Signal Ground Pin 6 —- CAN + (at PCM) Pin 11 — Module Communications Network B Pin 13 — PCM connection \u2013 called \u2018FESP\u2019 ? Pin 14 — CAN \u2013 (at PCM) Pin 16 — 12 volt (battery)<\/p>\n\n\n\n
My two principal concerns —-<\/h4>\n\n\n\n
1) The \u2018Check Engine\u2019 ( \u2018MIL\u2019 ) light has been on steady over a month or so; have been shopping around for a good, mid \u2013 priced reader \/scanner to find out what\u2019s going on ; 2) Next Spring, I want to replace the CD\/Radio ( called the \u2018 Audio Control Module \u2018 by Ford ) with a JVC KD-R420 CD\/Radio, which I previously used in a \u201894 Ford Escort —- this unit has only the 12v steady, 12v ACC, ILLUM and GRD wires, apart from the speakers.
From what I\u2019ve been reading lately, if I needed to use the Reader\/Scanner after changing the CD radio unit, I would not only NOT BE ABLE to use it, but I could BLOW it as well ! Really — excuse me ?<\/p>\n\n\n\n
From the Tech Rep<\/h4>\n\n\n\n
Here is an excerpt from a reply I got from a tech rep with a prominent reader\/scanner maker on this point —–
\u201c A vehicle that has an aftermarket radio installed most LIKELY WILL NOT WORK WITH AN OBD2 CODE READER because ALL VEHICLES OBD2 PORT use the RADIO\/ACCESSORY FUSES to power on an OBD2 code reader. If you have installed an aftermarket radio, most likely THOSE ACCESSORY FUSES WILL NO LONGER POWER ON THE OBD2 CODE READER. \u201c
Do you agree with this statement ?<\/strong>
After I examined my vehicle\u2019s service manual wiring and component diagrams, I found the following —-
1) The DLC is powered ONLY by its OWN 12v steady hot wire on Pin 16, and has its own SEPARATE fuse; 2) The CD\/Radio (\u2018Audio Control Module\u2019) ALSO has its own separate fuses (powered by different 12v steady hot and 12v ACC wires); 3) A \u2018power point\u2019 is used for a CIGARETTE LIGHTER — again, a separate wire and fuse.
Now, I am familiar with the VW\/Audi \u2018aftermarket radio\u2019 problem ( the Pin 7 \u2018K \u2013 Line\u2019 thing ) —- but I can\u2019t see HOW the above quoted scenario applies to my vehicle.
If you (or someone else with better knowledge of this) can enlighten me as to what to do about this, or if you need more information, please let me know asap.
Thanx loads —- Chris <\/p>\n\n\n\n\n\n\n\n
I do not agree with the quoted statement. However if a factory scan tool reader tech is informing you that their product will not work, you might want to steer clear of that particular model. <\/p>\n\n\n\n
That being said, you will want to choose a scan tool that will not only do OBD II but also CAN. As your vehicle uses CAN. <\/p>\n\n\n\n
