B2603 SHIFT POSITION STATUS

Description

INFOID:0000000003814981

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

DTC Logic

INFOID:0000000003814982

DTC DETECTION LOGIC

NOTE:
• If DTC B2603 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to

SEC-28, "BCM : DTC Logic"

.

• If DTC B2603 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer to

SEC-30, "BCM : DTC Logic"

.

• If DTC B2603 is displayed with DTC B210F for IPDM E/R, first perform the trouble diagnosis for DTC B210F.

Refer to 

SEC-107, "DTC Logic"

.
