Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




The control modules exchange information over a network via a standardized serial communication interface - CAN (Controller Area Network). Control modules transmit and receive information. Diagnostic trouble code (DTC) ABS-0091 is stored if the ABS control module registers that communication is missing or subject to interference.

Note! In the event of an ABS system communication fault it is not possible to communicate with the ABS control module. Therefore it will only be possible to read off the fault if it is intermittent.

Substitute value
- CAN communication blocked.
- Anti-spin function blocked.

Possible source
- Contact resistance in terminals.
- Open-circuit in one or both signal cables.
- Short-circuit to ground, voltage or each other in one or both signal cables.
- Interference in wiring.
- Defective control module.

Fault symptom[s]
- ABS warning lamp lit.
- Anti-spin warning lamp lit.
- Brake circuit not functioning, warning lamp lit.
- Anti-spin does not function.
