Rear vehicle monitoring control module (RH)

1.  Remove the trunk end trim. (See TRUNK END TRIM REMOVAL/INSTALLATION.)

2.  Remove the rear scuff plate. (See REAR SCUFF PLATE REMOVAL/INSTALLATION.) (5HB, Wagon)

3.  Remove the tire house trim. (See TIRE HOUSE TRIM REMOVAL/INSTALLATION.) (5HB, Wagon)

4.  Remove the trunk side upper trim. (See TRUNK SIDE UPPER TRIM REMOVAL/INSTALLATION.) (5HB, Wagon)

5.  Remove the trunk side trim. (See TRUNK SIDE TRIM REMOVAL/INSTALLATION.)

6.  Measure the rear vehicle monitoring control module terminal voltage using the rear wiring harness connector in the position shown in the figure.

Note
•  The rear vehicle monitoring control module connector cannot be connected to a tester due to the module's water-resistance processing, therefore the rear wiring harness connector is used for measuring the terminal voltage.
•  If the terminal voltage is not as indicated in the table, replace the short wiring harness connector.
―  If the system does not operate normally even though the related wiring harness and short cord are normal, replace the rear vehicle monitoring control module (RH).
