• Ignition off
• Disconnect central electronic module (CEM) connector D.

  Check central electronic module (CEM) connector D. Check for contact resistance and oxidation. Check for damage carefully.

  Check the ground lead between central electronic module (CEM) terminal #D6 (#6) and the ground terminal. Check for an open-circuit. Check for loose connections. Check for contact resistance and oxidation. With the ignition on, the drop in voltage between the ground connection for the central electronic module (CEM) and the ground terminal must not be greater than 0.5 V.

  Remedy as necessary.
