WIRING DIAGRAM







PROCEDURE

1. INSPECT FUSE (MPX-B, D/C CUT)

(a) Remove the MPX-B and D/C CUT fuses from the engine room No. 1 relay block.

(b) Measure the resistance of the fuses.

Standard resistance:

Below 1 Ohms

NG -- REPLACE FUSE
OK -- Continue to next step.

2. CHECK WIRE HARNESS (COWL SIDE JUNCTION BLOCK RH - BATTERY AND BODY GROUND)





(a) Disconnect the DK and DD junction block connectors.

(b) Measure the voltage and resistance of the wire harness side connectors.

Standard voltage:





Standard resistance:





NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN ON PROBLEM SYMPTOMS TABLE
