WARNING: This page is about a different car, the 2012 Ford F550 Super Duty and 2012 Ford F450 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: If equipped, turn the Power Take-Off (PTO) unit off to make sure test results are correct. For a description of PTO operation, refer to TRANSMISSION ELECTRONIC CONTROL SYSTEM . The PCM self-test is not accessible when the PTO is in operation.

After a road test, with the engine and transmission at normal operating temperature and before disconnecting any connectors, use the scan tool to perform the self-test procedure. Refer to the INTRODUCTION - GASOLINE MODELS for diagnosis and testing of the PCM.
