Circuit/System Testing

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, remove the fuse that supplies voltage to terminal 5 X2 of the K20 engine control module. Verify the fuse is OK.
      NOTE: This DTC will only set if the fuse is open and the circuits are not grounded. The ignition voltage circuits must be tested thoroughly for an intermittent short to ground.
    • If the fuse is open, test the ignition voltage circuit between the open fuse and the K20 engine control module terminal 5 X2 for an intermittent short to ground.
  2. Install the fuse.
  3. Disconnect the harness connectors of the K20 engine control module.
  4. Ignition ON, load test for B+ on the ignition circuit terminal 5 X2 of the K20 engine control module connector.
    • If less than B+, repair the ignition circuit for an open/high resistance.
  5. If all circuits/connections test OK, replace the K20 engine control module.
