Fault Codes
The list below identifies the fault codes that are gener-
ated by the TEC controller to identify an electrical sys-
tem malfunction (fault) that occurred during machine
operation. Use the InfoCenter Display for fault retrieval.
NOTE: The following list of fault codes identifies elec-
trical problems that typically will prevent normal ma-
chine operation. The InfoCenter Display will identify
existing faults if they should occur. Fault codes 13
through 25 identify problems with inputs (e.g. switches,
sensors) to the TEC controllers. For input problems, use
the InfoCenter Display to check t he different switch po si-
tions before removing or replacing the component.
NOTE: Fault codes 26 through 62 identify problems
with outputs (e.g. solenoid coils, light bulbs) from the
TEC controllers. These output problems might involve
issues with the wire harness or the actual output device
(solenoid coil or bulb).
