Computed Timing Check

1. Disconnect the SPOUT connector.
2. Start the engine and allow to idle.
3. While observing ignition timing with a timing light, install the SPOUT connector.
a. If the ignition timing changed when the SPOUT connector was installed continue with engine running self test.
b. If the ignition timing did not change when the SPOUT connector was installed continue with engine running test and look for code 213/18.
If the code is present, ignore any other codes and refer to the appropriate code chart for code 213/18.
If the code is not present, continue with the engine running test as directed in the test.
