Diagnostic Aids

WARNING: This page is about a different variant/trim than selected.

If vehicle speed is not detected by the ECM, the ECM will set DTC P0500.
A communication error, U-code, may exist between the ECM and TCM, which may cause DTC P0500 to set.
If TCM DTC P0722 or P0723 are set, diagnose these DTCs first. The ECM may also set a DTC P0700, requesting the MIL illumination from the TCM.
