.

1.

CHECK CVT SHIFT SELECTOR SWITCH FUNCTION

1. Turn ignition switch ON.

2. Select “SFT P -MET”, “SFT N -MET” and "SFT PN/N SW" in DATA MONITOR mode with CONSULT.

Possible cause

B2604

PNP/CLUTCH SW

The following states are detected for 5 seconds 
while ignition switch is ON:
• P/N position signal is sent  from TCM but shift 

position signal input (CAN) from TCM is other 
than P (Park)  and N (Neutral)

• P/N  position signal is not sent from TCM but 

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

• Harness or connectors

(CAN communication line is open 
or shorted.)

• Harness or connectors

(TCM circuit is open or shorted.)

• TCM
