B2604 SHIFT POSITION

B2604 SHIFT POSITION

Description

INFOID:0000000009950150

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

DTC Logic

INFOID:0000000009950151

DTC DETECTION LOGIC

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

BCS-40, "DTC Logic"

.

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

BCS-41, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Turn ignition switch ON under the following conditions and wait 1 second or more.

2.

Check “Self-diagnosis result” using CONSULT.

Is DTC detected?

YES

>> Go to 

SEC-62, "Diagnosis Procedure"

.

The following states are detected while ignition 
switch is ON.
• There is park/neutral position signal input but 

shift position signal input (CAN) from TCM is oth-
er than P or N

• There is not park/neutral position signal input but 

shift position signal input (CAN) from TCM is P or 
N

• Harness or connectors 

(Transmission range switch circuit 
is open or shorted)

• Transmission range switch
• BCM
