DESCRIPTION
WIRING DIAGRAM
INSPECTION PROCEDURE
HINT: Operating the ignition switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.
PROCEDURE
1. CHECK HARNESS AND CONNECTOR (ECM - BATTERY AND BODY GROUND)
(a) Disconnect the A24 and D74 ECM connectors.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
(c) Measure the voltage according to the value(s) in the table below.
Standard voltage:
Result
D -- REPAIR OR REPLACE HARNESS OR CONNECTOR
C -- REPLACE ECM
B -- REPLACE ECM
A -- REPLACE ECM
