DTC CONFIRMATION PROCEDURE

CAUTION:

Always drive vehicle at a safe speed.

NOTE:

If “DTC CONFIRMATION PROCEDURE” has been previously performed, always turn ignition switch OFF.

Then wait at least 10 seconds before performing the next test.

1.

CHECK DTC DETECTION

With CONSULT-III

1. Turn ignition switch ON.

2. Select “DATA MONITOR”.

3. Start engine and maintain the following conditions for at least 30 consecutive seconds.

With GST

Follow the procedure “With CONSULT-III”.
Is “P0776 PRS CNT SOL/B FCTN” detected?

YES

>> Go to 

TM-333, "Diagnosis Procedure"

.

NO

>> Check intermittent incident. Refer to 

GI-42, "Intermittent Incident"

.

Diagnosis Procedure

INFOID:0000000004201911
