INSPECTION PROCEDURE

PROCEDURE

1. CHECK WIRE HARNESS (TC of DLC3 - HYBRID VEHICLE CONTROL ECU)
(a) Disconnect the D1 connector from the DLC3 and H29 connector from the hybrid vehicle control ECU.





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






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (DLC3 - HYBRID VEHICLE CONTROL ECU)
OK -- Continue to next step.
2. CHECK WIRE HARNESS (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 (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 -- REPLACE HYBRID VEHICLE CONTROL ECU
