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.
Replacing The Component
The engine control module (ECM) has registered an internal fault.
If the fault is intermittent, it has been registered previously but is no longer present. Intermittent faults may be due to interference at start or may be a different type of fault that occurs on different occasions. The fault is evaluated depending on how it occurs.
Ensure that the software in the Engine control module (ECM) is correct by downloading it again.
If the fault recurs, replace the control module.
In the event of a permanent fault, replace the control module.
Remedy as necessary.
