DTC CONFIRMATION PROCEDURE
CAUTION: Always drive vehicle at a safe speed.
NOTE: Immediately after performing any "DTC CONFIRMATION PROCEDURE", always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT
Diagnosis Procedure
1.CHECK DTC WITH ECM
With CONSULT
2.CHECK DTC WITH TCM
With CONSULT
Perform "Self Diagnostic Results" in "TRANSMISSION".
3.DETECT MALFUNCTIONING ITEMS

Diagnosis Procedure
1.CHECK CONNECTOR
Turn the ignition switch OFF.
Disconnect the battery cable from the negative terminal.
Check the following terminals and connectors for damage, bend and
loose connection (unit side and connector
side).

Description
The IPDM E/R (intelligent power distribution module engine room) controls the
headlamp high relay based on inputs from the BCM over the CAN communication
lines. When the headlamp high relay is energized, power flows through fuses
48 and 49, located in the IPDM E/R. Power then flow ...
