DTC 78 - Right Front Solenoid Circuit Open Or Shorted To Battery: Notes
NOTE:
For circuit and connector terminal identification, see WIRING DIAGRAMS
.
EBCM can detect a solenoid that cannot be energized due to an open in its circuitry, or a solenoid that is always energized due to a short to battery between the driver circuit and the solenoid. An open will not allow proper ABS operation, but the short to battery simply turns the solenoid on. A path for base brakes is still allowed once the motor re-homes and the check ball is lifted off its seat during initialization.
NOTE:
Test numbers refer to test numbers on diagnostic chart.
- Checks for a short to voltage in the control circuit of the solenoid.
- Checks for an open in the control circuit of the solenoid.
- Checks solenoid coil for proper resistance.
- Checks for an open in the solenoid ground circuit.
- Checks for a possible intermittent malfunction in the solenoid circuit due to poor terminal contact.
