Parking Sensor Control Module Inspection: Notes
- Disconnect the negative battery terminal. (Refer to NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
- Remove the glove compartment. (Refer to GLOVE COMPARTMENT REMOVAL/INSTALLATION .)
- Remove the parking sensor control module. (Refer to PARKING SENSOR CONTROL MODULE REMOVAL/INSTALLATION .)
- Connect the negative battery terminal. (Refer to NEGATIVE BATTERY TERMINAL 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) and related wiring harnesses.
- If the system does not operate normally even though the inspection items are normal, replace the parking sensor control module.
