NO.2 BSM OFF INDICATOR LIGHT DOES NOT ILLUMINATE WHILE BSM SYSTEM IS OFF [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 8-PIN TYPE]

id0903n1990400

2 | BSM OFF indicator light does not illuminate while BSM system is OFF
DESCRIPTION | • BSM indicator light does not illuminate even though BSM OFF switch turns off after ignition switch is turned to ON position.
Possible Causes | • Malfunction in BSM OFF switch related parts ― BSM OFF switch malfunction (stuck at off) ― Open circuit in wiring harness between BSM OFF switch and BSM control module (RH) terminal E ― Open circuit in wiring harness between BSM OFF switch and ground • Instrument cluster does not illuminate BSM OFF indicator light ― BSM control module (RH) malfunction ― Communication error between BSM control module (RH) and instrument cluster ― Instrument cluster malfunction

Diagnostic Procedure

Step | Inspection | Action
--- | --- | ---
1 | VERIFY DTCs • Retrieve DTCs from the BSM control module (RH) and instrument cluster using the M-MDS. (See DTC INSPECTION [INSTRUMENT CLUSTER].) (See DTC INSPECTION [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 8-PIN TYPE].) • Are any DTCs displayed? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [INSTRUMENT CLUSTER].) (See DTC TABLE [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 8-PIN TYPE].)
No | Go to the next step.
2 | INSPECT IF MALFUNCTION IS IN BSM OFF SWITCH OR INSTRUMENT CLUSTER • Monitor the BSM control module (RH) PID BSM_OFF_IL using the M-MDS. • Turn the BSM OFF switch on and off. • Does the PID BSM_OFF_IL monitoring value turn on and off according to the BSM OFF switch operation? | Yes | Go to Step 5.
No | Go to the next step.
3 | INSPECT BSM OFF SWITCH • Inspect the BSM OFF switch. (See BLIND SPOT MONITORING (BSM) OFF SWITCH INSPECTION.) • Is the BSM OFF switch normal? | Yes | Go to the next step.
No | Replace the BSM OFF switch. (See BLIND SPOT MONITORING (BSM) OFF SWITCH REMOVAL/INSTALLATION.)
4* | INSPECT BSM OFF SWITCH RELATED WIRING HARNESS • Inspect for an open circuit in the following: ― Between BSM OFF switch and BSM control module (RH) terminal E ― Between BSM OFF switch and ground • Is an open circuit detected? | Yes | Repair or replace malfunctioning part.
No | Replace the BSM control module (RH). (See BLIND SPOT MONITORING (BSM) CONTROL MODULE REMOVAL/INSTALLATION [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 8-PIN TYPE].)
5 | INSPECT IF MALFUNCTION IS IN INSTRUMENT CLUSTER OR BSM CONTROL MODULE (RH) • Turn on the BSM OFF indicator light using check code 26 of the instrument cluster input/output check mode function. (See INSTRUMENT CLUSTER INPUT/OUTPUT CHECK MODE.) • Does the BSM OFF indicator light illuminate? | Yes | Replace the BSM control module (RH). (See BLIND SPOT MONITORING (BSM) CONTROL MODULE REMOVAL/INSTALLATION [BLIND SPOT MONITORING (BSM) CONTROL MODULE CONNECTOR 8-PIN TYPE].)
No | Replace the instrument cluster. (See INSTRUMENT CLUSTER REMOVAL/INSTALLATION.)
