NOTICE:
Inspect the fuse for circuits related to this system before performing the following procedure.
PROCEDURE
1. | CHECK ILLUMINATION CONTROLLED BY RHEOSTAT SWITCH |
(a) Perform the following procedure and check that the illumination controlled by the rheostat switch illuminates properly.
(1) If the vehicle is in a bright area, move it to a dark area.
HINT:
When the vehicle is in a bright area, the switch illumination may not turn on due to the auto dimmer function.
(2) If the light control switch is in the AUTO position, turn it to the tail or head position.
HINT:
If the light control switch is in the AUTO position, the switch illumination will not turn on unless the surrounding area is dark.
Result | Proceed to |
---|---|
Any of the illumination controlled by the rheostat switch does not illuminate properly. | A |
All of the illumination controlled by the rheostat switch illuminates properly. | B |
HINT:
The shift lever illumination and panel switch illumination are controlled by the rheostat switch. If either of these has a malfunction, such as an open circuit, the remote touch (remote operation controller assembly) switch illumination is affected and cannot be controlled by the rheostat switch.

|
2. | REPAIR OR REPLACE ILLUMINATION CONTROLLED BY RHEOSTAT SWITCH |
(a) Repair or replace the part with the malfunctioning illumination that is controlled by the rheostat switch.
NEXT | ![]() | GO TO STEP 3 |
3. | CHECK SYMPTOMS |
(a) Perform the following procedure, operate the rheostat switch again, and check if illumination brightness adjustment is possible (including adjustment of other devices such as the radio receiver assembly). (1) Check if the remote touch (remote operation controller assembly) is in self-diagnostic mode. If it is, cancel self-diagnostic mode. Click here HINT: When the remote touch (remote operation controller assembly) is in self-diagnostic mode, the remote touch (remote operation controller assembly) switch illumination may remain on. (2) If the vehicle is in a bright area, move it to a dark area. HINT: When the vehicle is in a bright area, the switch illumination may not turn on due to the auto dimmer function. (3) If the light control switch is in the AUTO position, turn it to the tail or head position. HINT: If the light control switch is in the AUTO position, the switch illumination will not turn on unless the surrounding area is dark.

4. | REMOTE TOUCH (REMOTE OPERATION CONTROLLER ASSEMBLY) SELF CHECK (SWITCH ILLUMINATION CHECK) |
(a) Activate self-diagnostic mode.
Click here
(b) Operate the remote touch screen diagonally from the upper left to the lower right and check that the brightness of the switch illumination changes. NOTICE: Since the remote touch screen may recognize a pinch in/out or flick operation if operated with 2 fingers, always use 1 finger to operate the remote touch screen in self-diagnostic mode. OK: Brightness of the switch illumination changes according to remote touch screen operation. |

5. | CHECK HARNESS AND CONNECTOR (ILLUMINATION SIGNAL) |
(a) Disconnect the J154 remote touch (remote operation controller assembly) connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
Tester Connection | Condition | Specified Condition |
---|---|---|
J154-2 (ILL+) - Body ground | Light control switch in tail or head position | 11 to 14 V |
NG | ![]() | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
6. | CHECK HARNESS AND CONNECTOR (REMOTE TOUCH (REMOTE OPERATION CONTROLLER ASSEMBLY) - COMBINATION METER ASSEMBLY) |
(a) Disconnect the J154 remote touch (remote operation controller assembly) connector.
(b) Disconnect the J10 combination meter assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
J154-5 (ILL-) - J10-39 (ILL-) | Always | Below 1 Ω |
J154-5 (ILL-) or J10-39 (ILL-) - Body ground | Always | 10 kΩ or higher |
OK | ![]() | REPLACE REMOTE TOUCH (REMOTE OPERATION CONTROLLER ASSEMBLY) |
NG | ![]() | REPAIR OR REPLACE HARNESS OR CONNECTOR |
