Begin the system diagnosis with
Diagnostic System Check - Alternative Fuels (Engine Controls)
.
The Diagnostic System Check-Engine Controls will provide the following
information:
• | The identification of the control modules which command the system |
• | The ability of the control modules to communicate through the
serial data circuit |
• | The identification of any stored diagnostic trouble codes (DTCs)
and the codes' statuses |
The use of the Diagnostic System Check-Engine Controls will identify
the correct procedure for diagnosing the system and where the procedure is
located.
