PARKING SENSOR CONTROL MODULE INSPECTION

id092200023600

  Caution
  • When the trailer switch (dealer option) is switched ON (operational), the parking sensor buzzer does not sound. If the parking sensor control module is inspected, perform the inspection after the trailer switch (dealer option) is switched off (non-operational).

1. Remove the trunk box. (See TRUNK BOX REMOVAL/INSTALLATION.)

2. 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 parking sensor control module.
