what is the gross vehicle weight???

Customer: replied 5 months ago.
Under 8600 i forgot to tell i have this code since i change the ABS module you think they give module for over 8600

first, how did you determine the module was bad???

the code indicates a wire harness issue not a component issue.

what was the part number of the module they gave you???

* The Traction Control indicator turns ON.

* The driver information center displays the Service Stability System message.

Conditions for Clearing the DTC

The EBCM clears the history DTC when a current DTC is not detected in*****cycles.

No garbage

Customer: replied 5 months ago.
i have trac and stability

ok, let me check

what was the original code before replacing the module

are any lights on at the dash???

Customer: replied 5 months ago.
I do not the code before but the technician tell me it is not the same for sureABS and Track controle light is on

the module does not match up to trac and stability.

still checking

I would call this guy back and have him find the old abs module. have him verify the numbers. it looks like he may have installed the wrong module.
