DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1.

Turn ignition switch OFF and wait at least 12 minutes.

2.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 12 minutes.

>> With consult: GO TO 2.
>> Without consult: GO TO 3.

2.

PERFORM DTC CONFIRMATION PROCEDURE-1

With CONSULT

1.

Start the engine and warm it up to normal operating temperature.

2.

—
—

At an engine restart by stop/start system, 
the voltage drop is not allowable less than 
Approx. 0.1 V when the engine restart by-
pass relay becomes closed from the open 
status, and this condition is repeated three 
times in a row.

• Harness or connectors

(Engine restart bypass relay circuit is open 
or shorted.)
(Engine restart bypass control relay circuit 
is open or shorted.)

• Engine restart bypass relay
• Engine restart bypass control relay
