DIAGNOSTICS AND TROUBLESHOOTING

 

These controllers detect a wide variety of faults or error conditions. Faults can be detected by the operating 
system or by the VCL code. This section describes the faults detected by the operating system. Diagnostics 
information can be obtained in either of two ways:   
(1) by reading the display on a hand-held or PC programmer or   
(2)  by  observing  the  fault  codes  issued  by  the  Status  LEDs.  See  Table  4  for  a  summary  of  LED  display 
formats. 
 
The pair of LEDs built into the controller (one red, one yellow) produce flash codes displaying all the currently 
set faults in a repeating cycle. Each code consists of two digits. The red light flashes once, indicating that the 
number of times the yellow light flashes below is the first digit of the fault code, and the red light flashes twice, 
indicating that the number of times the yellow light flashes below is the second digit of the fault code. 
Example: red light flashes once, followed by yellow light flashes four times.Then the red light blinks twice, 
then the yellow light blinks twice, so the fault code is 42. Please refer to the list of fault information in this 
manual for relevant fault codes and causes. 
The Throttle Wiper Low indicates that the accelerator output is low on the hand-held programmer fault code 
table.

 

 

The controller's two LEDs will display this repeating pattern 

 

The numerical codes used by the yellow LED are listed in the troubleshooting table, which also lists possible 
fault causes and describes the conditions that set and clear each fault. 
 
Summary of LED display formats 
The two LEDs have four different display modes, indicating the type of information they are providing: 

DISPLAY 

STATUS 

Neither LED illuminated 

Controller is not powered on/ vehicle has dead battery/ or severe damage. 

Yellow LED flashing 

Controller is operating normally. 

Yellow and red LEDs both on solid  Controller is in Flash program mode. 
Red LED light on solid 

No software loaded, or an internal hardware fault detected by the 
Supervisor or Primary microprocessor. Cycle KSI to clear. Reload 
software or replace controller if necessary. 

Red LED and yellow LED flash 
alternately 

Controller has detected a fault. 2-digit code flashed by   yellow LED 

identifies the specific fault; one or two flashes by red LED indicate 
whether first or second code digit will follow. 

 
Troubleshooting 

The troubleshooting chart provides the following information on all the controller faults: 

  fault code 

  fault name as displayed on the programmer's LCD 

  the effect of the fault 

  possible causes of the fault 

  fault set conditions 

  fault clear conditions. 

Whenever a fault is encountered and no wiring or vehicle fault can be found,shut off KSI and turn it back on 
to see if the fault clears. If it does not, shutoff KSI and remove the 35-pin connector. Check the connector for 
corrosion or damage, clean it if necessary, and re-insert it.
