Diagnostic Trouble Code Descriptions

Carry out On-Board Diagnostics

NOTE: If equipped, turn the Power Take-Off (PTO) unit off to ensure correct test results. On-Board Diagnostic is not accessible when the PTO is in operation.

After a road test, with the vehicle warm and before disconnecting any connectors, carry out the Quick Test using the scan tool.
