Press the INFORMATION button (Item 1) to cycle the
DATA DISPLAY (Item 2) [Figure 294] until the service
code screen is displayed. If more than one SERVICE
CODE is present, the codes will scroll on the DATA
DISPLAY.
NOTE: Corroded or loose earths can cause multiple
service codes and / or abnormal symptoms.
All instrument panel lights flashing, alarm
sounding, headlights and taillights flashing,
could indicate a bad earth. The same
symptoms could apply if the voltage is low,
such as loose or corroded battery cables. If
you observe these symptoms, check earths
and positive leads first.
Deluxe Instrumentation Panel
The optional Deluxe Instrumentation Panel offers an
additional view of service codes that includes a brief
description.
The last 40 codes stored in history can also be viewed
