Turn ON the ignition with the engine OFF. Does the Red Brake indicator illuminate? If so, go to step 9 . If not, go to next step.
- Test the signal circuit of the park brake switch for a high resistance or an open. Did you find and correct the condition? If so, go to step 17 . If not, go to step 11 .
- Test the signal circuit of the brake fluid level switch for a high resistance or an open. Did you find and correct the condition? If so, go to step 17 . If not, go to next step.
- Test the ground circuit of the brake fluid level switch for a high resistance or an open. Did you find and correct the condition? If so, go to step 17 . If not, go to step 12 .
