Diagnostic Procedure

Step

Inspection

Action
1
VERIFY IF MALFUNCTIONING LOCATION IS BLIND SPOT MONITORING (BSM) CONTROL MODULE (LH) DEPENDING ON REPEATABILITY
•  Clear the DTC for the blind spot monitoring (BSM) control module using the M-MDS.
•  Switch the ignition ON (engine off or on) and wait for 2.5 s or more.
•  Retrieve the blind spot monitoring (BSM) control module DTCs using the M-MDS.
•  Is the same DTC displayed?
Yes
Replace the blind spot monitoring (BSM) control module (LH), then go to the next step.
(See BLIND SPOT MONITORING (BSM) CONTROL MODULE REMOVAL/INSTALLATION.)
No
Go to the next step.
2
VERIFY IF OTHER DTCs DISPLAYED
•  Are any other DTCs displayed?
Yes
Repair or replace the malfunctioning part according to the applicable DTC troubleshooting.
(See DTC TABLE [BLIND SPOT MONITORING (BSM) SYSTEM].)
No
DTC troubleshooting completed.
