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

BCS-66, "DTC Logic"

.

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

BCS-67, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Shift the selector lever to the P position.

2.

Turn ignition switch ON and wait 5 seconds or more.

3.

Shift the selector lever to the N position and wait 5 seconds or more.

4.

Shift the selector lever to any position other than P and N, and wait 5 seconds or more.

5.

Check DTC in “Self Diagnostic Result” mode of “BCM” using CONSULT.

Is DTC detected?

YES

>> Go to 

SEC-71, "Diagnosis Procedure"

.
