2.INSPECT FUSE (S/ROOF, ECU-IG LH, AM2)

  1. Remove the S/ROOF and ECU-IG LH fuses from the cowl side junction block LH.

  1. Remove the AM2 fuse from the cowl side junction block RH.

  1. Measure the resistance of the fuses.

    Standard resistance:
    Below 1 Ω



NG
REPLACE FUSE
OK


3.INSPECT COWL SIDE JUNCTION BLOCK LH (LH-IG 2 RELAY)
