Initial Inspection and Diagnostic Overview

Remote Control Back Rest System

INSPECTION

1. WIRING DIAGRAM
Refer to "Remote Control Back Rest System" in the wiring diagram. [Ref. to, WIRING DIAGRAM, Remote Control Back Rest System.] WI-99,Remote Control Back Rest System

2. DIAGNOSTIC CHART







3. CHECK REMOTE CONTROL BACK REST SYSTEM FUSE

Remove the fuse (FB-6) of remote control back rest system, and visually check.

Is the fuse blown out?
- Yes -> Replace the fuse.
- No -> Check the power supply and ground circuits.

4. CHECK POWER SUPPLY AND GROUND CIRCUIT
1. Check power supply circuit.
1. Disconnect the remote control back rest switch.
2. Turn the ignition switch to ON.
3. Measure the voltage between harness connector terminal and chassis ground.

Connector & terminal
RH side:
(R172) No. 5 (+) - Chassis ground (-):

LH side:
(R173) No. 5 (+) - Chassis ground (-):

Is the voltage 12 V or more?
- Yes -> Go to step 2.
- No -> Check the harness between the remote control back rest switch and fuse.

2. Check ground circuit.
Measure the resistance between harness connector terminal and chassis ground.

Connector & terminal
RH side:
(R172) No. 1 - Chassis ground:

LH side:
(R173) No. 1 - Chassis ground:

Is the resistance less than 10 ohms when the switch is ON?
- Yes -> Go to step 3.
- No -> Check the switch.

3. Check power supply circuit.
1. Connect the remote control back rest switch.
2. Disconnect the remote control back rest actuator.
3. Turn the ignition switch to ON.
4. Measure the voltage between harness connector terminal and chassis ground.

Connector & terminal
RH side:
(R170) No. 1 (+) - Chassis ground (-):

LH side:
(R171) No. 1 (+) - Chassis ground (-):

Is the voltage 12 V or more when the switch is ON?
- Yes -> Go to step 4.
- No -> Check the harness between the remote control back rest switch and actuator.

4. Check ground circuit.
Measure the resistance between harness connector terminal and chassis ground.

Connector & terminal
RH side:
(R170) No. 2 - Chassis ground:

LH side:
(R171) No. 2 - Chassis ground:

Is the resistance 1 M ohm or more when the switch is ON?
- Yes -> Perform the inspection of actuator unit.
- No -> Repair the harness of ground circuit.

5. INSPECTION OF SWITCH UNIT

1. Disconnect the remote control back rest switch connector.
2. Measure the resistance between terminals of remote control back rest switch connector.

Connector & terminal
RH side:
(R172) No. 5 - (R172) No. 1:

LH side:
(R173) No. 5 - (R173) No. 1:

Is the resistance less than 10 ohms when the switch is ON?
- Yes -> Normal operation.
- No -> Replace the switch.

6. INSPECTION OF ACTUATOR UNIT

1. Disconnect the connector of actuator.
2. Connect the battery to the actuator connector.

Connector & terminal
RH side:
(R170) No. 1 (+) - (R170) No. 2 (-):

LH side:
(R171) No. 1 (+) - (R171) No. 2 (-):

Does the actuator operate?
- Yes -> Normal operation.
- No -> Replace the actuator.
