Self Test Function (continued)
Pressing SELECT changes the display as shown.
The fuel sensor resistance is shown in Ohms in the clock
display.
Pressing SELECT changes the display as shown.
A value of 0 to a maximum of 4.5 Volts will be displayed in
the clock display depending on the position of the throttle.
*
Pressing SELECT changes the display as shown.This
monitors transistor block output.
When TR is displayed, pressing the reset button once will
initiate the controller to test all the transistor block outputs 1
through 20. If a faulty output is detected it will stop at that
output number. Monitor will display "ELEC. PROBLEM"
(short circuits only).
To detect open circuits, select different services in turn and
check screen display:
e.g. '1' = closed circuit
'0' = open circuit
