INSPECTION PROCEDURE

1.INSPECT FUSE (TV, ACC, ECU-IG RH)

  1. Remove the TV fuse from the cowl side junction block LH.

  1. Remove the ACC and ECU-IG RH fuses from the cowl side junction block RH.

  1. Measure the resistance of the fuses.

    Standard resistance:
    Below 1 Ω



NG
REPLACE FUSE
OK


2.CHECK WIRE HARNESS (MULTI-DISPLAY - BATTERY AND BODY GROUND)
