INSPECTION PROCEDURE

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
