Do your Chevrolet Check Engine Light (CEL) or other warning lights such as ABS, Airbag, and TPMS stay on? Learn how to fix it by following the procedures below.
What you will need
- YOUCANIC UCAN-2 Scanner – to diagnose engine, check engine light, ABS, transmission, airbag, air conditioner, and any control unit or problem.
- YOUCANIC UCAN-1 Scanner – to diagnose the check engine light only.
- Park the Chevrolet on a level surface and set the parking brakes.
- Open the driver’s door and locate the OBD-2 port.
- Plug your scanner into the OBD2 port.
- Turn on the ignition by turning the key to position II. If your Chevrolet has a START/STOP button feature, press the button without pressing the brake pedal.
- Allow your scanner to turn on. Follow the prompts on your scanner to read fault codes.
- Diagnose the Chevrolet Check Engine Light.
Diagnose Chevrolet ABS Anti-lock Brake System
An ABS light cannot be diagnosed with a generic OBD2 scanner. You will need an ABS diagnostic scanner.
Diagnose Chevrolet SRS Airbag Light
Similar to the ABS light, your Chevrolet SRS Airbag lights cannot be diagnosed with a basic OBD2 scanner. You will need a multi-system scanner.
Knowing which scanner to use to read Chevrolet fault codes can be challenging. Basic OBD2 scanners can only retrieve fault codes from your Chevrolet Engine Control Unit ECU. Those are faults that trigger the Check Engine warning light.
You will need an advanced scanner to diagnose other systems such as ABS and Airbag/SRS warning lights. The procedure for reading Chevrolet fault codes is similar, regardless of which scanner you use.
