Without RPO JL4
DTC C0245 (W/O JL4)
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 Descriptor
This diagnostic procedure supports the following DTC:
DTC C0245 EBCM Control Valve Circuit
Conditions for Running the DTC
^ The ignition is ON.
^ The vehicle speed is greater than 6 km/h (4 mph).
Conditions for Setting the DTC
The EBCM detects an internal malfunction.
Action Taken When the DTC Sets
^ The EBCM disables the DRP/ABS.
^ The ABS indicator turns ON.
^ The red brake warning 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 DTC's 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.
