4.

Check the voltage between EGR cooler bypass valve control solenoid valve harness connector and
ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 3.

3.

DETECT MALFUNCTIONING PART

Check the following.
• Harness connectors E8, F1
• Harness for open or short between IPDM E/R and EGR cooler bypass valve control solenoid valve

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

4.

CHECK EGR COOLER BYPASS VALVE CONTROL SOLENOID VALVE GROUND CIRCUIT FOR OPEN

AND SHORT

1.

Turn ignition switch OFF.

2.

Disconnect ECM harness connectors.

3.

Check the continuity between EGR cooler bypass valve control solenoid valve harness connector and
ECM harness connector.

DTC No.

PC415 COMMUNICATION CIRCUIT

PC415 COMMUNICATION CIRCUIT

Description

INFOID:0000000006496728

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.
