B2604 PNP SWITCH

Description

INFOID:0000000005515540

BCM confirms the shift position with the following 4 signals.
• CVT shift selector (detention switch)
• Transmission range switch
• P position signal from IPDM E/R (CAN)
• P position signal from TCM (CAN)

DTC Logic

INFOID:0000000005515541

DTC DETECTION LOGIC

NOTE:
• If DTC B2604 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to

SEC-32, "BCM : DTC Logic"

.

• If DTC B2604 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer to

SEC-34, "BCM : DTC Logic"

.

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Start the engine under the following conditions and wait for at least 1 second.

-

Selector lever is in the P or N position

-

Depress the brake pedal

2.

Check “Self diagnostic result” with CONSULT-III.

Is DTC detected?

YES

>> Go to 

SEC-69, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000005515542

1.

CHECK DTC WITH TCM

Check “Self diagnostic result” with CONSULT-III. Refer to 

TM-122, "DTC Index"

.

Is the inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace the malfunctioning parts.

2.

CHECK TRANSMISSION RANGE SWITCH CIRCUIT 1

1.

Turn ignition switch OFF.

2.

Disconnect TCM connector and BCM connector.

3.

Check continuity between TCM harness connector and BCM harness connector.

Is the inspection result normal?

YES

>> GO TO 5.

NO

>> GO TO 3.

DTC No.
