C0044

DTC C0044 Right Front Dump Solenoid Circuit Shorted:

Dump Solenoid Circuit Schematic:

CIRCUIT DESCRIPTION
When the RF dump solenoid is needed (see Antilock Brake System, Description and Operation), the Electronic Brake Control Module (EBCM) will ground the solenoid circuit to energize the coil within the solenoid. This will open the dump valve by the magnetic force created by the solenoid coil. Conditions For Setting the Diagnostic Trouble Codes (DTC) High voltage on EBCM solenoid driver circuit when expected to be low (solenoid energized

ACTION TAKEN WHEN THE DTC SETS
^ ANTILOCK indicator lamp is illuminated
^ ABS is disabled

NOTE: DTC C0044 is an Ignition Latched DTC which indicates the above is true until the ignition is turned to OFF (even if the cause of the DTC is intermittent).

DIAGNOSTIC AIDS
DTC C0044 is usually set by a shorted solenoid within the EBCM. The dump solenoid coils are located within the EBCM and are not serviceable. If the test does not repair the DTC, the EBCM must be replaced.
If DTC C0044 is set with other DTCs, check for a poor EBCM ground or poor EBCM power feed.

TEST DESCRIPTION
The numbers below refer to the numbers on the diagnostic chart.
2. Inspect EBCM 2-way harness connector for damage.
3. Check EBCM power and ground circuits.
