DTC CONFIRMATION PROCEDURE

PRECONDITIONING

CONSULT

  1. Ignition switch ON.

  2. Select “T LAMP LH CIRC MALFUNCTN” and “T LAMP RH CIRC MALFUNCTN” in “Data monitor” mode of “IPDM E/R”.

  3. Check the monitor status.

    Monitor item Monitor status
    T LAMP LH CIRC MALFUNCTN 0
    1
    T LAMP RH CIRC MALFUNCTN 0
    1

What is the monitor status?

“0”>>

GO TO 2.

“1”>>

A short circuit is detected multiple times in the license plate lamp, side marker lamp, tail lamp or power supply circuit, and damage accumulates at the Smart FET inside the IPDM E/R. For this reason, IPDM E/R does not turn ON the Smart FET. Because the DTC cannot be reproduced in this state, perform Diagnosis Procedure and replace IPDM E/R after the malfunctioning part is repaired. Refer to Removal and Installation.

PERFORM DTC CONFIRMATION PROCEDURE

CONSULT

  1. Ignition switch OFF.

  2. Ignition switch ON.

  3. Turn lighting switch 1ST.

  4. Select “Self diagnosis result” mode of “IPDM E/R”.

  5. Check DTC.

Is DTC detected?

YES>>

Refer to DTC Diagnosis Procedure.

NO-1>>

To check malfunction symptom before repair: Refer to Intermittent Incident.
