METER CONTROL SWITCH SIGNAL CIRCUIT
METER CONTROL SWITCH SIGNAL CIRCUIT
Diagnosis ProcedureINFOID:0000000009461733
Regarding Wiring Diagram information, refer to MWI-32, "Wiring Diagram".
1.CHECK METER CONTROL SWITCH SIGNAL
1. Turn ignition switch ON.
2. Check voltage between the following terminals of the meter control switch harness connector M158.
Is the inspection result normal?
YES >> Inspection End.
NO >> GO TO 2.
2.CHECK METER CONTROL SWITCH HARNESS
1. Turn ignition switch OFF.
2. Disconnect combination meter harness connector M26 and meter control switch harness connector
M158.
3. Check continuity between combination meter harness connector M26 and meter control switch harness connector M158.
4. Check continuity between combination meter harness connector and ground.
Is the inspection result normal?
YES >> Inspection End.
NO >> Repair or replace harness or connectors.

STEERING SWITCH
STEERING SWITCH
DescriptionINFOID:0000000009461735
When one of the steering switches is pushed, the resistance in the steering switch changes the signal to
identify which button is controlling the information display.
Diagnosis ProcedureINFOID:0000000009461736
Regarding Wiring Diagram information, refer to MWI-32, "Wiring Diagram".
1.CHECK STEERING SWITCH CIRCUIT
1. Turn ignition switch OFF.
2. Disconnect combination meter harness connector M24 and spiral cable harness connector M30.
3. Check continuity between combination meter har ness connector M24 and spiral cable harness connector
M30.
4. Check continuity between combination meter harness connector M24 and ground.
Is the inspection results normal?
YES >> Inspection End.
NO >> Repair or replace harness or connectors.
