DIAGNOSIS SYSTEM (BCM)
The BCM records the following condition at the moment a particular DTC is detected.
 Vehicle Speed
 Odo/Trip Meter
 Vehicle Condition (BCM detected condition)
IGN Counter
IGN counter indicates the number of times that ignition switch is turned ON after DTC is detected.
 The number is 0 when a malfunction is detected now.
 The number increases like 1 → 2 → 3...38 → 39 after returning to the normal condition whenever ignition
switch OFF → ON.
 The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.

DTC DETECTION LOGIC
DTC CONFIRMATION PROCEDURE
1.PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch ON under the following conditions (start the engine), and wait for at least 2 seconds.
- Selector lever is in the P or N position.
- Do not depress brake pedal.
2. Check “Self diagnostic result” with CONSULT-III.
Is DTC detected?
YES >> Go to PCS-49, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000003805736
1.CHECK DTC WITH IPDM E/R
Check “Self diagnostic result” with CONSULT-III. Refer to PCS-120, "
DTCIndex".
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace malfunctioning parts.
2.CHECK FUSE
Check that the following fuse is not fusing.
Is the fuse fusing?
YES >> Repair the applicable circuit. And then replace the fuse.
NO >> GO TO 3.
3.CHECK IGNITION RELAY FEEDBACK INPUT SIGNAL
1. Turn ignition switch OFF.
2. Disconnect BCM connector.
3. Check voltage between BCM harness connector and ground.
DTC No.Trouble diagnosis
