TROUBLE DIAGNOSES WORK FLOWPFP:00004
When Displaying CAN Communication System ErrorsNKS00349
WHEN A MALFUNCTION IS DETECTED BY CAN COMMUNICATION SYSTEM

CAN communication line is open. (CAN-H, CAN-L, or both)

CAN communication line is shorted. (Ground, between CAN lines, or other harnesses)

The areas related to CAN communication of unit is malfunctioning.
WHEN A MALFUNCTION IS DETECTED EXCEPT CAN COMMUNICATION SYSTEM

Removal and installation of parts: When the units that perform CAN communication or the sensors related
to CAN communication are removed and installed, malfunction may be detected (or DTC other than CAN
communication may be detected).

Fuse blown out (removed): CAN communication of the unit may be stopped at such time.

Low voltage: If the voltage decreases because of battery discharge when IGN is ON, malfunction may be
detected by self-diagnosis according to the units.

4. ECM AND IPDM E/R INTERNAL CIRCUIT INSPECTION
1. Remove ECM and IPDM E/R from vehicle.
2. Check resistance between ECM terminals.
3. Check resistance between IPDM E/R terminals.
OK or NG
OK >> GO TO 5.
NG >> Replace ECM and/or IPDM E/R.
5. CHECK SYMPTOM
1. Fill in described symptoms on the column “Symptom” in the check sheet.
2. Connect all connectors, and then make sure that the symptom is reproduced.
Check results
Reproduced>>GO TO 6.
Not reproduced>>Refer to LAN-14, "
Example of Filling in Check Sheet When Initial Conditions Are Not
Reproduced" .
6. CHECK UNIT REPRODUCIBILITY
Performs the following procedure for each unit on the CAN network, and then perform reproducibility test.
1. Turn ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Disconnect the unit connector.
4. Connect the battery cable to the negative terminal.
5. Make sure that the symptom filled in the “Symptom” of the check sheet is reproduced. NOTE:
Malfunction (related to a unit that the connector is disconnected) is reproduced. Do not confuse the mal-
function with the symptom filled in the column of “Symptom” on the check sheet.
Inspection results
Reproduced>>Connect the disconnected connector. Check other units applying the above procedure.
Not reproduced>>Replace the unit that the connector is disconnected.
IPDM E/R Ignition Relay Circuit InspectionNKS0039D
Check the following. If no malfunction is found, replace the IPDM E/R.

IPDM E/R power supply circuit. Refer to PG-26, "IPDM E/R Power/Ground Circuit Inspection" .
