ABS Communication Not Supported
2000 Mustang 3.8L V6Question Re:ABS Communication Not Supported
2000 Mustang 3.8L V6 with ABS and Traction control.
The ABS light comes on and TC (traction control) is disengaged. This is an intermittent problem.
I Attempted to scan for ABS code using a scanner with ABS capability but receive return message that says, this vehicle does not support ABS communication
The auto shop also tried to scan for ABS codes but failed to establish the communication link too. Tested the scanner by scanning a 1999 Mustang V6 with ABS & TC and received return message: No ABS codes detected, which is reasonable since the 99 was not experiencing an ABS problem.
Question: Why does my 2000 Mustang V6 not support ABS communication? Are ABS codes issued and just not accessible? Answer:
As you probably suspected, from having tried obtaining trouble codes from scanning the 1999 Ford Mustang V6 car and receiving a response, there should be communication to your OBD scanner
via the ALDL connector in your 2000 Mustang V6 with ABS and traction control.
My experience has been that although this is not totally uncommon, it does seem to pop up from time to time on 1999 to 2001 Mustangs (either V8 or V6 powered).
You are going to need to first go through the system and figure out what is preventing the components from talking
. Grab you copy of the repair manual and/or a wiring diagram for your 2006 Mustang, a can of contact cleaner and a small brush.
2000 Mustang ABS Circuit Testing
Typically, on these cars, when you see the "ABS Communication Not Supported" message, you will have a small issue somewhere in the system that needs to be taken care of.
Once that is solved, you should be able to clear out the code and do a normal scan. Grab some contact cleaner and a small brush
.Communication Circuit Diagnostic StepsCheck terminal pins for power to the circuit (see your wiring diagram) and for corrosion
Check ground supply pins for continuity and corrosion
Check all four wheel sensors for corrosion and connections
Clean wheel sensor components
Check and clean ABS module ground connections in the engine bay
Check Brake pedal position switch for correct voltage and resistance values
Chances are, after you go through this procedure, one or more of these connections will be the culprit. After that, you should have communication via the connector in the key on engine off position (KOEO). In the process, you may also find that it cures your intermittent ABS problem.
And if not, you'll be in a position to find out what the component issue really is.
Hope that helps.
