INSPECTION PROCEDURE
NOTE:
When the distance control ECU and/or ECM are replaced with a new one, initialization must be performed Installation.

PROCEDURE

1. CHECK WIRE HARNESS (TERMINAL TC of DLC3 - ECM)




(a) Disconnect the A10 connector from the ECM.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (DLC3 - ECM)
OK -- Continue to next step.
2. CHECK WIRE HARNESS (TERMINAL CG of DLC3 - BODY GROUND)




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






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (DLC3 - BODY GROUND)
OK -- Continue to next step.
3. CHECK WIRE HARNESS (TERMINAL TC of DLC3 - BODY GROUND)




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






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR OR EACH ECU
OK -- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE
