DTC DETECTION LOGIC
DTC CONFIRMATION PROCEDURE
1. PERFORM SELF DIAGNOSTIC RESULT
1. Press the push-button ignition switch under the following conditions, and wait for at least 1 second.
2. Perform self diagnostic result.
Is DTC B261A detected?
YES >> Refer to PCS "Diagnosis Procedure".
NO >> Inspection End.
Regarding Wiring Diagram information, refer to PCS "Wiring Diagram".
1. CHECK PUSH-BUTTON IGNITION SWITCH OUTPUT SIGNAL (PUSH-BUTTON IGNITION SWITCH)
1. Disconnect push-button ignition switch connector.
2. Check voltage between push-button ignition switch connector M25 terminal 8
and ground.
Is the inspection result normal?
YES >> GO TO 2.
NO >> GO TO 4.
2. CHECK IGNITION SWITCH OUTPUT SIGNAL (IPDM E/R)
Check voltage between IPDM E/R connector E47 terminal 81 and ground.
Is the inspection result normal?
YES >> GO TO 3.
NO >> Replace IPDM E/R. Refer to PCS "Removal and Installation".
3. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (IPDM E/R)
1. Turn ignition switch OFF.
2. Disconnect IPDM E/R connector E47 and BCM connector M98.
3. Check continuity between IPDM E/R connector E47 terminal 81 and
push-button ignition switch connector
M25 terminal 8.
4. Check continuity between IPDM E/R connector E63 terminal 38 and ground.
Is the inspection result normal?
YES >> Refer to GI "Intermittent Incident".
NO >> Repair or replace harness or connectors.
4. CHECK IGNITION SWITCH OUTPUT SIGNAL (BCM)
Check voltage between BCM connector M98 terminal 76 and ground.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Replace BCM. Refer to BCS "Removal and Installation".
5. CHECK PUSH-BUTTON IGNITION SWITCH CIRCUIT (BCM)
1. Turn ignition switch OFF.
2. Disconnect BCM connector M98 and IPDM E/R connector E47.
3. Check continuity between BCM connector M98 terminal 76 and push-button
ignition switch connector
M25 terminal 8.
4. Check continuity between BCM connector M98 terminal 76 and ground.
Is the inspection result normal?
YES >> Refer to GI"Intermittent Incident".
