INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (TC of DLC3 - ECM)

(a) Disconnect the ECM connector.

(b) Measure the resistance according to the value(s) in the table below.

Standard resistance:





HINT
* *1: for 1UR-FSE
* *2: for 2GR-FSE

(c) Reconnect the ECM connector.

NG -- REPAIR OR REPLACE WIRE HARNESS AND CONNECTOR (DLC3 - ECM)
OK -- Continue to next step.

2. CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND)





(a) Measure the resistance according to the value(s) in the table below.

Standard resistance:
