DTC DETECTION LOGIC

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

BCS-47, "DTC Logic"

.

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

BCS-48, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Shift the selector lever to the P position.

PNP/CLUTCH SW

The following states are detected for 5 seconds 
while ignition switch is ON.
• P/N position signal is sent  from transmission 

range switch but shift position signal input 
(CAN) from TCM is other than P and N

• P/N  position signal is not sent from transmis-

sion range switch but shift position signal input 
(CAN) from TCM is P or N

• Harness or connectors

(The CAN communication line is 
open or shorted.)

• Harness or connectors 

(Transmission range switch circuit 
is open or shorted.)

• Transmission range switch
• TCM
