Sensor ‑
Mounting Error
• Before troubleshooting, verify that the trailer has been parked on level
ground.
• Verify that the TABS-6 Advanced ECU has been programmed with the
proper ECU orientation, tire size and tone ring settings.
• Verify that the TABS‑6 Advanced module has been mounted as per the
Installation Guidelines (See Troubleshooting Section G, page 33):
- The configured ECU orientation matches the actual ECU
orientation.
‑ Verify that wheel speed sensors are installed correctly (left/right)
(See Figure 19)
• After repairs or if no issues are found, then clear diagnostic codes.
• If diagnostic code persists, contact the BCVS local representative before
replacing the TABS‑6 Advanced module.

Out Of Range
• Before troubleshooting, verify that the trailer has been parked on level
ground.
• Verify that the TABS‑6 Advanced module has been mounted as per the
Installation Guidelines.
• Perform a Lateral Acceleration Sensor (installation angle) Component
Test using the Bendix ® ACom ® Diagnostic Software (version 6.1 or
higher):
‑ Verify the roll angle of the TABS‑6 Advanced module is within ±5° as
measured from a flat horizontal plane.
• After repairs or if no issues are found, then clear the diagnostic codes.
• If diagnostic code persists, contact the BCVS local representative before
replacing the TABS‑6 Advanced module.

Error
• Before troubleshooting, verify that the trailer has been parked on level
ground.
• Verify that the TABS‑6 Advanced module has been mounted as per the
Installation Guidelines.
• Perform a Lateral Acceleration Sensor (installation angle) Component Test
using the Bendix ® ACom ® Diagnostic Software (version 6.1 or higher).
‑ Verify the roll angle of the TABS‑6 Advanced module is within ±5° as
measured from a flat horizontal plane.
‑ If the roll angle is out of tolerance, clear the diagnostic code and test
drive the vehicle.
• After repairs or if no issues are found, then clear the diagnostic codes.
• If diagnostic code persists, contact the BCVS local representative before
replacing the TABS‑6 Advanced module.

Found
• Verify that the TABS‑6 Advanced module has been mounted as per the
Installation Guidelines:
- TABS-6 Advanced module mounted either in 0°, 90°, 180° or 270°
orientation.
• If the ECU has been configured for an external lateral acceleration sensor:
- Check for corroded/damaged wiring or connectors between the ECU
and the external lateral acceleration sensor.
- Verify correct wiring between the ECU and the external lateral
acceleration sensor.

- Signal Not
Found
• Check for corroded/damaged wiring or connectors between the ECU and
the external lateral acceleration sensor.
• Verify correct wiring between the ECU and the external lateral
acceleration sensor.
• After repairs or if no issues are found, then clear the diagnostic codes.
• If diagnostic code persists, replace the external lateral acceleration
sensor.
