WIRING DIAGRAM
INSPECTION PROCEDURE
| 1.INSPECT FUSE (RAD NO. 1, RAD NO. 2, ACC) |
Remove the RAD NO. 1 and RAD NO. 2 fuses from the engine room No. 1 relay block.
Remove the ACC fuse from the cowl side junction block RH.
Measure the resistance of the fuses.
- Standard resistance:
- Below 1 Ω
| 2.CHECK WIRE HARNESS (STEREO COMPONENT AMPLIFIER - BATTERY AND BODY GROUND) |
Disconnect the V29 and V31 amplifier connectors.
Measure the voltage of the wire harness side connectors.
- Standard voltage:
Tester Connection
