B2605 SHIFT POSITION

Description

INFOID:0000000009950154

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:0000000009950155

DTC DETECTION LOGIC

NOTE:
• If DTC B2605 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to

BCS-40, "DTC Logic"

.

• If DTC B2605 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010. Refer to

BCS-41, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

1.
