Component Testing
- Ignition OFF, disconnect the harness connector at the power brake booster actuator.
- Test for infinite ohms of resistance between the control terminal 1 and ground of the power brake booster actuator.
- If less than infinite ohms, replace the vacuum brake booster assembly.
- Test for 3 ohms of resistance between each terminal at the power brake booster actuator.
- If the test is infinite resistance, replace the vacuum brake booster assembly.
