DTC CONFIRMATION PROCEDURE
1. PERFORM DTC CONFIRMATION PROCEDURE
1. Press the push-button ignition switch under the following conditions, and wait for at least 1 second.
- CVT selector lever is in the P or N position.
- Release the brake pedal.
2. Check “Self diagnostic result” with CONSULT-III.
Is DTC detected? YES >> Go to PCS-75, "Diagnosis Procedure".
NO >> Inspection End.
Diagnosis Procedure
1. CHECK PUSH-BUTTON IGNITION SWITCH OPERATION
Press push-button ignition switch and check if it turns to ON.
Does ignition switch turn to ON? YES >> GO TO 2
NO >> GO TO 4
2. CHECK IGNITION SWITCH OUTPUT SIGNAL (IPDM E/R)
1. Disconnect push-button ignition switch.
2. Check voltage between IPDM E/R harness connector and ground.
Is the inspection result normal? YES >> GO TO 3
NO >> Replace IPDM E/R. Refer to PCS-48, "Removal and Installation".
3. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (IPDM E/R)
1. Disconnect IPDM E/R and BCM.
2. Check continuity between IPDM E/R harness connector (A) and push-button ignition switch harness connector (B).
3. Check continuity between IPDM E/R harness connector and ground.
Is the inspection result normal? YES >> GO TO 6
NO >> Repair or replace harness.
4. CHECK IGNITION SWITCH OUTPUT SIGNAL (BCM)
1. Disconnect push-button ignition switch.
2. Check voltage between BCM harness connector and ground.
Is the inspection result normal? YES >> GO TO 5
NO >> Replace BCM. Refer to BCS-96, "Removal and Installation".
5. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (BCM)
1. Disconnect BCM and IPDM E/R.
2. Check continuity between BCM harness connector (A) and push-button ignition switch harness connector (B).
3. Check continuity between BCM harness connector and ground.
Is the inspection result normal? YES >> GO TO 6
NO >> Repair or replace harness.
6. CHECK INTERMITTENT INCIDENT
Refer to GI-42, "Intermittent Incident".
>> Inspection End.

Description BCM controls the various electrical components and simultaneously supplies power according to the power supply position. BCM checks the power supply position internally. DTC Logic ...Other materials:
Headlamp (halogen)
Description
The IPDM E/R (intelligent power distribution module engine room) controls the
headlamp low relay based on
inputs from the BCM over the CAN communication lines. When the headlamp low
relay is energized, power
flows through fuses 51 and 52, located in the IPDM E/R. Power then flows ...
B2612 steering status
Description
There are 2 switches in the steering unit. IPDM E/R compares those 2 switches
conditions to judge the
present steering status and transmit the result to BCM via CAN communication.
