1) Turn ON the ignition switch.
2) Check the BSM OFF indicator light. Does the indicator light illuminate for approximately 3 seconds and then turn OFF?
Yes
=>Go to Indicator light illumination check using MID mode switch.
No
=>Go to Instrument panel cluster warning light/indicator light operation inspection.
1) Turn OFF the ignition switch.
2) Turn ON the ignition switch.
3) Inspect the operation of other warning lights and indicator lights excluding the BSM OFF indicator light. Is the result normal?
Yes
=>Go to Instrument panel cluster replacement.
No
1) Turn OFF the ignition switch.
2) Inspect the METER 5A fuse. Is the result normal?
Yes
=>Go to Inspection for open circuit in instrument panel cluster power supply circuit.
No
Replace the fuse. If the fuse blows out again, repair the short to ground in the circuits relating to the METER 5A fuse.
1) Disconnect the instrument panel cluster harness connector (B7).
2) Connect a test lamp between the ignition power supply circuit of the instrument panel cluster harness connector (pin 2 of B7) and the body ground.
Refer to "LHD Combination Meter" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Combination Meter" in the ETM (wiring diagram). (Open using the ETM viewer.).
3) Turn ON the ignition switch. Does the test lamp illuminate?
Yes
=>Go to Instrument panel cluster harness connector inspection.
No
Repair the open circuit or high resistance in the ignition power supply circuit between the METER 5A fuse and the instrument panel cluster (pin 2 of B7).
1) Inspect for poor connections at the instrument panel cluster harness connector (pin 2 of B7). Is the result normal?
Refer to "LHD Combination Meter" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Combination Meter" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to Instrument panel cluster replacement.
No
Repair the connections as necessary.

Procedure completion
1) Turn off the blind spot monitor function with the Settings of Multi-Information Display in the instrument panel cluster. Does the BSM OFF indicator light illuminate?
Yes
Go to Intermittent conditions of radar sensor system.
Refer to "233.Driver Assistance System 46D.Symptom(Radar Sensor) intermittent conditions of radar sensor system".
No
=>Go to Body CAN communication circuit inspection and Chassis CAN communication circuit inspection.
1) Perform the Body CAN communication circuit inspection and Chassis CAN communication circuit inspection.
Refer to "64.Body Control 10I.Troubleshooting(Central GateWay) body CAN communication circuit inspection".
Refer to "64.Body Control 10I.Troubleshooting(Central GateWay) chassis CAN communication circuit inspection".
Procedure completion
=>Go to Indicator light illumination follow-up check.
1) Turn OFF the ignition switch.
2) Securely connect all of the disconnected harness connectors.
3) Turn ON the ignition switch.
4) Turn off the blind spot monitor function with the Settings of Multi-Information Display in the instrument panel cluster. Does the BSM OFF indicator light illuminate?
Yes
No
=>Go to Radar sensor (Left) replacement.
Note
Refer to "9.Body, Cab, Accessories 9E.Instrumentation, Driver Info. radar sensor removal".
Refer to "9.Body, Cab, Accessories 9E.Instrumentation, Driver Info. radar sensor installation".
Refer to "9.Body, Cab, Accessories 9E.Instrumentation, Driver Info. radar sensor setting".
Procedure completion
1) Securely connect all of the disconnected harness connectors.
2) Turn OFF the ignition switch for 30 seconds or more.
3) Perform a test drive.
4) Check the BSM OFF indicator light, as well as the vehicle behavior and drivability. Does the vehicle run properly without the BSM OFF indicator light illuminating or a DTC being set?
Yes
The system is normal.
No
Go to Diagnostic system check-radar sensor system.
