Wheel System, Traction 190Service Manual – SC6500
Fault Code Table (Troubleshooting Chart)
The troubleshooting chart, provides the following information on each wheel drive controller fault:
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 (Key Switch)
and turn it back on to see if the fault clears. If it does not, shut off KSI and remove the low current 35-pin
connector from the drive controller. Check the connector for corrosion or damage, clean it if necessary, and
re-insert it.
Note: Some of the codes listed in the table are for circuits that are not utilized on the SC6500.
