Electric Parking Brake Control Module Inspection
- Disconnect the electric parking brake control module connector. (See ELECTRIC PARKING BRAKE CONTROL MODULE REMOVAL/INSTALLATION .)
- Attach the tester lead to the electric parking brake control module wiring harness-side connector and inspect voltage or continuity according to the Terminal Voltage Table (Reference) on the table.
- If not specified, replace the electric parking brake control module. (See ELECTRIC PARKING BRAKE CONTROL MODULE REMOVAL/INSTALLATION .)
