REAR VEHICLE MONITORING CONTROL MODULE INSPECTION

id092200146100

Rear vehicle monitoring control module (RH)

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.

1. Disconnect the negative battery cable.

2. Peel off the seaming welt.

3. Remove the following parts: (4SD)

(1) Trunk mat

(2) Trunk board

(3) Trunk end trim (See TRUNK END TRIM REMOVAL/INSTALLATION.)

(4) Trunk side trim (RH) (See TRUNK SIDE TRIM REMOVAL/INSTALLATION.)

4. Remove the following parts: (5HB)

(1) Trunk mat

(2) Trunk board

(3) Trunk end trim (See TRUNK END TRIM REMOVAL/INSTALLATION.)

(4) Rear scuff plate (RH) (See REAR SCUFF PLATE REMOVAL/INSTALLATION.)

(5) Tire house trim (RH) (See TIRE HOUSE TRIM REMOVAL/INSTALLATION.)

(6) Trunk side upper trim (RH) (See TRUNK SIDE UPPER TRIM REMOVAL/INSTALLATION.)

(7) Trunk side trim (RH) (See TRUNK SIDE TRIM REMOVAL/INSTALLATION.)

5. Remove the following parts: (Wagon)

(1) Trunk mat

(2) Trunk board

(3) Sub-trunk

(4) Trunk end trim (See TRUNK END TRIM REMOVAL/INSTALLATION.)

(5) Rear scuff plate (RH) (See REAR SCUFF PLATE REMOVAL/INSTALLATION.)

(6) Tire house trim (RH) (See TIRE HOUSE TRIM REMOVAL/INSTALLATION.)

(7) Trunk side upper trim (RH) (See TRUNK SIDE UPPER TRIM REMOVAL/INSTALLATION.)

(8) Trunk side trim (RH) (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.

• If the terminal voltage is not as indicated in the table, inspect the parts under “Inspection item (s)”.

― If the parts under “Inspection item (s)” are found to be normal, replace the rear vehicle monitoring control module (RH).
