Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




The control modules communicate with each other in a network via a standardized serial communication procedure - CAN (Controller Area Network) - for exchange of information. Control modules transmit and receive information. Diagnostic trouble code (DTC) ABS-0090 is stored if the ABS control module registers that communication is missing or subject to interference.

Substitute value
- CAN communication blocked.
- TRACS system is disengaged (cars equipped with TRACS only).
- Anti-spin function is blocked.

Possible source
- Defective control module.

Fault symptom[s]
- ABS warning lamp lit.
- Anti-spin warning lamp lit.
- Brake circuit not functioning, warning lamp lit.
- No vehicle speed displayed (because of missing signal to the combined instrument panel).
