- Remove the rear combination light. (See REAR COMBINATION LIGHT REMOVAL/INSTALLATION .)
- Remove the rear bumper. (See REAR BUMPER REMOVAL/INSTALLATION .)
- Connect the negative battery cable. (See NEGATIVE BATTERY CABLE DISCONNECTION/CONNECTION .)
- Verify that the voltages of each of the terminals are as indicated in the terminal voltage table (reference).
- If the voltage is not as specified in the terminal voltage table (reference), inspect the parts under Inspection item(s).
- If the system does not operate normally even though the inspection items are normal, replace the BSM control module.
