IMPORTANT:
It is recommend that Component Testing is performed before Circuit Testing when diagnosing the power brake booster actuator.
- Ignition OFF, disconnect the harness connector from the hill hold solenoid.
- Test for less than 5.0 ohm of resistance between the harness connector terminals and ground.
- If greater than 5.0 ohm, test the ground circuit for an open/high resistance.
- Connect a test lamp between the hill hold solenoid harness connector terminals. With a scan tool, command the HHV solenoid On and Off.
- If the test lamp remains OFF during the commands, test for a short to ground or an open/high resistance on either control circuit. If the circuits test normal, test or replace the power fuse.
- If all circuits test normal, test or replace the hill hold solenoid valve.
