INSPECTION PROCEDURE

PROCEDURE

1. CHECK BASIC FUNCTION (PUSH-BUTTON START FUNCTION)

(a) Check the basic function of the push-button start function.

OK:

Basic function operates normally.

NG -- GO TO SMART ACCESS SYSTEM WITH PUSH-BUTTON START (for Starting)
OK -- Continue to next step.

2. INSPECT FUSE (ECU-IG RH)

(a) Remove the ECU-IG RH fuse from the main body ECU RH.

(b) Measure the resistance of the fuse.

Standard resistance:

Below 1 Ohms

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

3. CHECK WIRE HARNESS (MAIN BODY ECU RH - BATTERY)





(a) Disconnect the DM junction block connector.

(b) Measure the voltage of the wire harness side connector.

Standard voltage:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

4. CHECK WIRE HARNESS (MAIN BODY ECU RH - BODY GROUND)





(a) Disconnect the DD junction block connector.

(b) Measure the resistance of the wire harness side connector.

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

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