DTC A077 - Left Front Solenoid Circuit Shorted To Ground: Notes

The EBCM identifies a solenoid that cannot be energized due to an open in its driver circuitry or a short to ground between the solenoid driver and the solenoid. These malfunctions can affect ABS operation since the flow of brake fluid to the caliper cannot be stopped, making ABS operation for that channel impossible.

1. Checks for a solenoid that is internally shorted to ground. Tester J 39200 is a DVOM with a 10-megohm input impedance.
2. Checks for a solenoid that is not within proper resistance values.
3. Indicates if a short to ground exists in the solenoid circuitry.
4. Checks for an open control circuit to the EBCM.
5. Checks for a possible intermittent malfunction in the solenoid circuitry due to poor terminal contact.
