Comments On Trouble Symptom

If the system is not turned on and off by operating the blind spot warning switch, a circuit (among the gateway-ECU, the blind spot warning light and ground), the gateway-ECU, or the BSW-ECU (master) may be defective.

NOTE: Prior to diagnosis, check the power supply circuit to the gateway-ECU. If no faults are detected, follow this troubleshooting procedure.
