NOTE:  For referrals to any chart not included in DIAGNOSTIC CHARTS, refer to COMPUTERIZED ENGINE CONTROLS.

To enter diagnostic mode, proceed as follows:

1.

Turn ignition "ON".

2.

Depress the "OFF" and "WARMER" buttons on the Climate Control Panel simultaneously and hold until all display panel segments illuminate
which indicates the beginning of the diagnostic readout. The purpose of illuminating the two display panels is to check that all segments of the
displays are working. If any of the segments are inoperative, the affected display panel will need to be diagnosed.
