- INSPECT FUSE (ECU-IG RH, MPX-B, D/C CUT)
- Remove the ECU-IG RH fuse from the cowl side junction block RH.
- Remove the MPX-B fuse from the engine room No. 1 relay block.
- Remove the D/C CUT fuse from the engine room No. 1 relay block.
- Measure the resistance of the fuses.
Standard resistance:
Below 1 Ω
NG: REPLACE FUSE
OK: Go to next step
- CHECK WIRE HARNESS (BATTERY - COMBINATION SWITCH - BODY GROUND)
- Disconnect the K22 switch connector.
- Measure the voltage and resistance of the wire harness side connector.
