DIAGNOSTICS AND TROUBLESHOOTING
PROGRAMMER DIAGNOSTICS
With a programmer, the diagnostics and troubleshooting process is more direct
than with the LED alone. The programmer presents complete diagnostic infor-
mation in plain languageno codes to decipher. Faults are displayed in the
Diagnostic Menu, and the status of the controller inputs/outputs is displayed in
the Test Menu.
The following 4-step process is generally used for diagnosing and troubleshooting
an inoperative vehicle: (1) visually inspect the vehicle for obvious problems;
(2) diagnose the problem, using the programmer; (3) test the circuitry with the
programmer; and (4) correct the problem. Repeat the last three steps as necessary
until the vehicle is operational.
Example: A vehicle that does not operate in forward is
brought in for repair.
STEP 1: Examine the vehicle and its wiring for any obvious
problems, such as broken wires or loose connections.
STEP 2: Connect the programmer, put it in diagnostic mode,
and read the displayed fault information. In this example, the
display shows No Faults Present, indicating that the control-
ler has not detected anything out of the norm.
STEP 3: Put the programmer in test mode, and observe the
status of the inputs and outputs in the forward direction. In
this example, the display shows that the forward switch did not
close when forward was selected, which means the problem
is either in the forward switch or the switch wiring.
STEP 4: Check or replace the forward switch and wiring and
repeat the test. If the programmer shows the forward switch
closing and the vehicle now drives normally, the problem has
been corrected.
Refer to the troubleshooting chart (Table 1) for suggestions covering a wide range
of possible faults.
