•  Instrument cluster malfunction

Diagnostic Procedure

Step

Inspection

Action

1
INSPECT IF MALFUNCTION IS IN BLIND SPOT MONITORING (BSM) SWITCH OR INSTRUMENT CLUSTER
•  Monitor the blind spot monitoring (BSM) control module (RH) PID BSM_OFF_IL using the M-MDS.
•  Turn the blind spot monitoring (BSM) switch on and off.
•  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.
•  Are any DTCs displayed?
Yes
Go to the applicable DTC inspection.
No
Go to the next step.
3
DETERMINE IF MALFUNCTION CAUSE IS INSTRUMENT CLUSTER OR BLIND SPOT MONITORING (BSM) CONTROL MODULE (LH)
•  Turn off all the indicator lights and warning lights in the instrument cluster using the simulation function WL+IL of the M-MDS instrument cluster.
•  Did the blind spot monitoring (BSM) OFF indicator light turn off?
Yes
Replace the blind spot monitoring (BSM) control module (LH).
No
Replace the instrument cluster.
