Output Diagnostic Test Mode (scan tool
function 03)


Notes:

Output Diagnostic Test Mode is only possible
when vehicle is stationary and engine is not
running!
If malfunctions are found during output
Diagnostic Test Mode, determine cause of
malfunction and replace instrument cluster if
necessary.

During the "output Diagnostic Test Mode"
function, all actuators that are installed in the
instrument cluster and coded are activated in
sequence.
There is also a simultaneous parallel sweep
through the indicator range of all analog display
instruments (Engine Coolant Temperature
(ECT) gauge, tachometer, speedometer, fuel
gauge)

The following tests are performed
simultaneously:

Sweep of coolant temperature needle through
entire display range
Sweep of tachometer needle through entire
display range
Sweep of speedometer needle through entire
display range
Sweep of fuel gauge needle through entire
display range
After sweep of display ranges, the following fixed
values are displayed:

Engine Coolant Temperature (ECT)
gauge:
1/2
Tachometer: 3000 RPM

Speedometer: 62 MPH
Fuel gauge:
1/2

Note:
Switching ignition on and off will stop any needle
