Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Retrieving Codes
When Mode II is accessed (engine NOT running), codes stored in ECU memory will be flashed by CHECK ENGINE light and red LED on side of ECU. A long flash (.6 second) indicates first digit of code. Short flashes (.3 second) indicate second digit of code. For example: 3 long flashes followed by 5 flashes of red LED (or CHECK ENGINE light) indicate a Code 35.
