Solenoid Tests

This function allows the technician to command a selected valve solenoid ON and OFF. Use the procedures below to verify proper operation of the electronic brake control module (EBCM) and brake pressure modulator valve (BPMV).

Outlet Valve Solenoid Test Procedure

1. Apply the parking brake fully.
2. Start the engine and allow the engine to idle.
3. Select the desired outlet Valve Solenoid Test on the scan tool.
4. Apply the brake and maintain steady pressure on the brake pedal.
5. Command the solenoid ON and verify that the brake pedal drops to the floor.

Inlet Valve Solenoid Test Procedure

1. Apply the parking brake fully.
2. Start the engine and allow the engine to idle.
3. Select the desired Inlet Valve Solenoid Test on the scan tool.
4. Apply the brake with very light pressure only enough to close the brake switch.
5. Command the solenoid ON and then immediately apply firm and steady pressure to the brake pedal.
6. The EBCM automatically de-energizes the solenoid after about 3 seconds. When this occurs, verify that the brake pedal drops about 2.2 cm (1 inch).
