BLIND SPOT MONITORING (BSM) OFF INDICATOR LIGHT DOES NOT ILLUMINATE WHILE BLIND SPOT MONITORING (BSM) SYSTEM IS OFF [BLIND SPOT MONITORING (BSM) SYSTEM (Australian specs.)]

id1503b2021000

Caution
•  Configuration cannot be implemented correctly if only the blind spot monitoring (BSM) control module (RH) is replaced. When replacing the blind spot monitoring (BSM) control module (RH), it is necessary to replace the blind spot monitoring (BSM) control module (LH) at the same time.

Description
BLIND SPOT MONITORING (BSM) OFF INDICATOR LIGHT DOES NOT ILLUMINATE WHILE BLIND SPOT MONITORING (BSM) SYSTEM IS OFF
•  Blind spot monitoring (BSM) warning light does not illuminate even though blind spot monitoring (BSM) switch turns off the system after ignition switch is turned to ON position.
Possible Causes
Note
•  The detection performance of the blind spot monitoring (BSM) control module has limitations and the blind spot monitoring (BSM) system may not operate normally. For the detection performance limitations, refer to the [BLIND SPOT MONITORING (BSM) CONTROL MODULE [Australian specs.]] in the technical guide.
•  Blind spot monitoring (BSM) control module (RH) malfunction
•  Connectivity master unit (CMU) malfunction
•  Instrument cluster malfunction

Diagnostic Procedure

Step

Inspection

Result

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.
(See DTC TABLE [CONNECTIVITY MASTER UNIT].)
No
Go to the next step.
3
INSPECT IF MALFUNCTION IS IN INSTRUMENT CLUSTER OR BLIND SPOT MONITORING (BSM) CONTROL MODULE (RH)
•  Turn on the blind spot monitoring (BSM) OFF indicator light using the M-MDS instrument cluster active command modes WL+IL.
•  Does the blind spot monitoring (BSM) OFF indicator light illuminate according to the active command modes?
Yes
Replace the blind spot monitoring (BSM) control module.
(See BLIND SPOT MONITORING (BSM) CONTROL MODULE REMOVAL/INSTALLATION [Australian specs.].)
No
Replace the instrument cluster.
