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.
Checking The Wiring
Click on the VCT2000 symbol.
Find out if the diagnostic trouble code (DTC) CEM-1A41 (A) is stored.
If there is a diagnostic trouble code (DTC) this means that the Start Control Unit (SCU) is defective and must be replaced.
Check the cables and connections between the Start Control Unit (SCU) and the Central electronic module (CEM).
Check the fuse for the ignition switch in the engine compartment fusebox.
Remedy as necessary.
