BLIND SPOT MONITORING (BSM) OFF INDICATOR LIGHT FALSE ILLUMINATION [BLIND SPOT MONITORING (BSM) SYSTEM]

id1503a3020000

Note

• If there is any vehicle malfunction complaint lodged by a customer, first perform malfunction diagnosis according to the troubleshooting procedure. (See FOREWORD [BLIND SPOT MONITORING (BSM) SYSTEM].)

Description

• The blind spot monitoring (BSM) OFF indicator light turns on while not under illumination conditions.

Possible malfunction

• The blind spot monitoring (BSM) control module (LH) cannot verify the blind spot monitoring (BSM) system operation / non-operation signal.

― Connectivity master unit (CMU) malfunction

― Blind spot monitoring (BSM) control module (LH) malfunction

• The instrument cluster cannot turn on the blind spot monitoring (BSM) OFF indicator light.

― Instrument cluster malfunction (illumination circuit malfunction)

Diagnostic Procedure

Step

Inspection

Action

1

DETERMINE IF CAUSE OF MALFUNCTION IS BLIND SPOT MONITORING (BSM) SYSTEM OPERATION / NON-OPERATION SIGNAL OR BLIND SPOT MONITORING (BSM) OFF INDICATOR LIGHT

•  Monitor the blind spot monitoring (BSM) control module (LH) PID BSM_OFF_IL using the M-MDS.
(See PID/DATA MONITOR INSPECTION [BLIND SPOT MONITORING (BSM) CONTROL MODULE].)

•  Turn the blind spot monitoring (BSM) switch on and off.
(See i-ACTIVSENSE PERSONALIZATION FEATURES SETTING PROCEDURE.)

•  Does the PID BSM_OFF_IL monitoring value turn on and off according to the blind spot monitoring (BSM) switch operation?

Yes

Go to Step 3.

No

Go to the next step.

2

INSPECT CONNECTIVITY MASTER UNIT (CMU)

•  Retrieve DTCs from connectivity master unit (CMU) using the M-MDS.
(See DTC INSPECTION [CONNECTIVITY MASTER UNIT].)

•  Are any DTCs displayed?

Yes

Go to the applicable DTC inspection.

(See DTC TABLE [CONNECTIVITY MASTER UNIT].)

No

Go to the next step.

3

DETERMINE IF MALFUNCTION CAUSE IS INSTRUMENT CLUSTER OR BLIND SPOT MONITORING (BSM) CONTROL MODULE (LH)

•  Illuminate all the indicator lights and warning lights in the instrument cluster using the simulation function WL+IL in the M-MDS instrument cluster.
(See ACTIVE COMMAND MODES INSPECTION [INSTRUMENT CLUSTER].)

•  Did the blind spot monitoring (BSM) OFF indicator light turn on.

Yes

Replace the blind spot monitoring (BSM) control module (LH).

(See BLIND SPOT MONITORING (BSM) CONTROL MODULE REMOVAL/INSTALLATION.)

No

Replace the instrument cluster.

(See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
