WIRING DIAGRAM

INSPECTION PROCEDURE

HINT
Operating the engine switch, any switches or any doors triggers related ECU and sensor communication with the CAN, which causes resistance variation.

PROCEDURE

1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

(a) Disconnect the cable from the negative (-) battery terminal before measuring the resistances of the main wire and the branch wire.

CAUTION:
Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to prevent airbag and seat belt pretensioner activation.

NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.

NEXT -- Continue to next step.

2. CHECK FOR OPEN IN CAN BUS WIRE (INTEGRATION CONTROL AND PANEL BRANCH WIRE)

(a) Disconnect the L35 integration control and panel connector.

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

Standard resistance:

NG -- REPAIR OR REPLACE INTEGRATION CONTROL AND PANEL BRANCH WIRE OR CONNECTOR (CANH, CANL)
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (INTEGRATION CONTROL AND PANEL - BATTERY AND BODY GROUND)

(a) Connect the cable to the negative (-) battery terminal.

NOTICE:
When disconnecting the cable, some systems need to be initialized after the cable is reconnected Repair Instruction - Initialization.

(b) Disconnect the L35 integration control and panel connectors.

(d) Measure the voltage according to the value(s) in the table below.

Standard voltage:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE INTEGRATION CONTROL AND PANEL ASSEMBLY Removal
