E109787E01


INSPECTION PROCEDURE

1.INSPECT FUSE (RAD NO. 1, RAD NO. 2, ACC)
  1. Remove the RAD NO. 1 and RAD NO. 2 fuses from the engine room No. 1 relay block.

  1. Remove the ACC fuse 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 (STEREO COMPONENT AMPLIFIER - BATTERY AND BODY GROUND)
