6.6 ERROR CODES:
The diagnostic system uses error codes between 1 and 499.
- The codes between 1 and 99 are the information codes.
They are never stored in the controller memory, hence can be displayed only in the [inputs/
outputs]=>[current error codes].
- The codes between 100 and 199 are the warning codes.
They are stored, they do not pertain to faults that can be repaired, but that need truck servicing: example,
electrobrake air gap setting.
- The codes between 200 and 499 are the error codes.
They are grouped into 3 parts:
1- From 200 to 299: fault in a controller input or output (external component fault, internal transistor
to control the output defective).
2- From 300 to 399: fault in controller power part.
3- From 400 to 499: internal fault between two microprocessors.
