DTC Description

INFOID:0000000010922303

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Harness or connectors

(Starter control relay circuit is shorted)

• Starter control relay
• BCM

FAIL-SAFE

—

DTC CONFIRMATION PROCEDURE

1.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Turn ignition switch ON.

2.

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

Is DTC detected?

YES

>> Refer to 

SEC-289, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to 

GI-44, "Intermittent Incident"

.

NO-2

>> Confirmation after repair: INSPECTION END

Diagnosis Procedure

INFOID:0000000010922304

1.

CHECK STARTER CONTROL RELAY INPUT SIGNAL

Check voltage between BCM harness connector and ground.

Is the inspection result normal?

YES

>> GO TO 4.

NO

>> GO TO 2.

2.

CHECK FUSE

Check that the following fuse is not blown

Is the fuse fusing?

YES

>> Replace the blown fuse after repairing the affected circuit if a fuse is blown.

NO

>> GO TO 3.

3.

CHECK STARTER CONTROL RELAY INPUT SIGNAL CIRCUIT

1.

Disconnect BCM connector and starter control relay connector.
