1807 4
SAS Datalink
Fault
ATC WL ESC Disabled
The steering wheel angle signal is not available after ignition on.
• Check CAN wiring between ABS-ECU and SAS for interruptions and short circuits. • Check for corroded or damaged wiring between the SAS and ESC Module. • Contact WABCO North America Customer Care at 855-228-3203 to check
parameter setting of ABS ECU and SAS compatibility.
1807 89 7 8 + 6
Steering Ratio
Fault
ATC WL ESC Disabled
The calculated steering ratio of the vehicle is not plausible.
• Check for correct mounting of the SAS and ESC module. • If work has been performed on the vehicle which affects the steering system or front
end alignment, perform SAS Calibration and ESC Initialization. Refer to Section 8.
1807 89 8 7 + 1
SAS
Calibration
Fault
ATC WL ESC Disabled
The Steering Angle Sensor calibration failed.
• Verify SAS is correctly mounted. • Perform SAS Calibration and ESC Initialization. Refer to Section 8.
1807 89 9 7 + 1
SAS CAN
Fault
(temp)
ATC W L
ESC Disabled
(temp possible)
Data communication faults with ESC module.
• Check harness between ABS ECU and SAS. • Check parameter setting of ABS ECU. • Check SAS operation if fault persists.
1807 89 12 8 + 6 SAS Failure ATC WL ESC Disabled
The Steering Angle Sensor is communicating an internal error to the ABS ECU.
• Check CAN wiring between ABS-ECU and SAS for interruptions and short circuits. • Check for corroded or damaged wiring between the SAS and ESC Module.
1807 89 13 8 + 6
SAS not
Calibrated
ATC WL ESC Disabled
The ECU has detected that SAS out of calibration.
• Follow the SAS calibration procedure. Refer to Section 8.
1807 89 14 8 + 6
SAS Internal
Fault
ATC WL ESC Disabled

Shorted to
UBATT
ATC WL ESC Disabled
Continuity between suspect ESC supply circuit and voltage supply (short circuit) is detected.
• Check CAN wiring between ABS-ECU and SAS for interruptions and short circuits. • Check for corroded or damaged wiring between the SAS and ESC Module. • Contact WABCO North America Customer Care at 855-228-3203 to check parameter
setting of ABS ECU and SAS compatibility.
