DIAGNOSTICS SERVICE CODES

Display

Figure 175

Press and hold the LIGHTS Button (1) [Figure 175] for
two seconds to view SERVICE CODES in the
HOURMETER / CODE DISPLAY (2). If more than one
SERVICE CODE is present, the codes will scroll on the
HOURMETER / CODE DISPLAY.

NOTE: Corroded or loose grounds can cause

multiple service codes and/or abnormal
symptoms. All instrument panel lights
flashing, alarm sounding, headlights and
taillights flashing, could indicate a bad
ground. The same symptoms could apply if
the voltage is low, such as loose or corroded
battery cables. If you observe these
symptoms, check grounds and positive leads
first.

SERVICE CODES may be either a word (3) [Figure 175]
or a number (4). (See the following pages for the number
codes.)

The following word errors may be displayed.

REPLY

One or both instrument panel(s) not

communicating with the controller.

INPUT

The controller not communicating with the

left instrument panel.

CODE

The controller is asking for a password.
