The "diagnostic display" mode is entered with the following procedure:
1) Turn on the ignition but don't start the engine.
2) Press the "reset" button to turn off any warning messages
3) Press and hold "options" , press "fuel" four times within a 10-second period.
When first engaged the on-board diagnostics go into an "automatic" mode.
The computer will show two kinds of codes, "current" and "history," designated "C" or "H".
A current code indicates a malfunction is present in the system whose module is displaying data.
A history code indicates a past problem.
When the screen displays "manual diagnostics," select the desired module by pressing the "options" button
to go forward or the "trip" button to go back.
Press "gauges" to go forward or
"fuel" to go back for each code under a module.
