U1000 CAN COMM CIRCUIT

Description

INFOID:0000000011280639

CAN communication allows a high rate of information transmission through the two communication lines

(CAN-H line and CAN-L line) connecting various control units in the system. Each control unit transmits/

receives data but selectively reads required data only.

Diagnosis Procedure

INFOID:0000000011377372

Regarding Wiring Diagram information, refer to 

PCS-25, "Wiring Diagram"

.

1.

 CHECK FUSE AND FUSIBLE LINKS

Check that the following IPDM E/R fuse or fusible links are not blown.

Is the fuse blown?

YES

>> Replace the blown fuse or fusible link after repairing the affected circuit.

NO

>> GO TO 2.

2.

 CHECK BATTERY POWER SUPPLY CIRCUIT

1. Disconnect IPDM E/R connector E118.

2. Check voltage between IPDM E/R connector E118 and ground.

Is the inspection result normal?

YES

>> GO TO 3.

NO

>> Repair or replace harness or connectors.

3.

 CHECK GROUND CIRCUIT

1. Disconnect IPDM E/R connectors E119, E120 and E121.

2. Check continuity between IPDM E/R connectors and ground.

Is the inspection result normal?

YES

>> Inspection End.

NO

>> Repair or replace harness or connectors.

Terminal No.
