Check Power Supply And Ground 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. 4 (+) - Chassis ground (-):

   LH side:

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

   Is the voltage 12 V or more?

   Yes

   Go to  2.

   No

   Check the harness between the remote control back rest switch and fuse.

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 Ω when the switch is ON?

Yes

Go to  3.

No

Check the switch.

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. 4 (+) - Chassis ground (-):

   LH side:

   (R171) No. 4 (+) - Chassis ground (-):

   Is the voltage 12 V or more when the switch is ON?

   Yes

   Go to  4.

   No

   Check the harness between the remote control back rest switch and actuator.

Measure the resistance 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 resistance 1 MΩ or more when the switch is ON?

Yes

Perform the inspection of actuator unit.

No

Repair the harness of ground circuit.
