POWER SUPPLY AND GROUND CIRCUIT

4.

Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> GO TO 11.

NO

>> Repair open circuit, short to ground or short to power in harness or connectors.

11.

CHECK 15 A FUSE

1.

Disconnect 15 A fuse (No. 50) from IPDM E/R.

2.

Check 15 A fuse.

Is the inspection result normal?

YES

>> GO TO 13.

NO

>> Replace 15 A fuse.

12.

CHECK ECM POWER SUPPLY CIRCUIT-VI

1.

Disconnect ECM harness connector.

2.

Disconnect IPDM E/R harness connector.

3.

Check the continuity between ECM harness connector and IPDM E/R harness connector.

4.

Also check harness for short to ground and short to power.

Is the inspection result normal?

YES

>> GO TO 13.

NO

>> Repair open circuit, short to ground or short to power in harness or connectors.

13.

CHECK INTERMITTENT INCIDENT

U0101 CAN COMM CIRCUIT

Description

INFOID:0000000005536533

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
