C0242

DTC C0241-C0243

Circuit Description
The ABS relay supplies battery voltage to 6 valve solenoids. The electronic brake control module (EBCM) microprocessor applies the grounds needed to activate each solenoid. The low side of each solenoid coil has a feedback circuit to the EBCM microprocessor. When a solenoid is commanded OFF, the feedback voltage is high. When a solenoid is commanded ON, the feedback voltage is low.

DTC Descriptors

The EBCM detects an internal malfunction.

Action Taken When the DTC Sets

C0241 and C0242
If equipped, the following actions occur:
^ The EBCM disables the DRP/ABS.
^ The ABS indicator turns ON.
^ The red brake warning indicator turns ON.

C0243
If equipped, the following actions occur:
^ The EBCM disables the ABS.
^ The ABS indicator turns ON.

Conditions for Clearing the DTC
The conditions for setting the DTC are no longer present and you use the scan tool Clear DTCs function.

Diagnostic Aids





An intermittent open/shorted solenoid DTC can be set by several different internal EBCM problems. Replace the EBCM if an open/shorted solenoid DTC continues to set intermittently.
