7 1
Internal Pressure
Sensor Range:
Control Port “P4”
•Verifythetrailer’scontrol(service)pressureis<130psi.
• After repairs — or if no issues are found — clear the diagnostic code.
• If the diagnostic code persists, contact your local Bendix
representative before replacing the Bendix
®
TABS‑6
™
Adv MC
module.

7 2
Internal Pressure
Sensor Range:
LoadPort“P42”
•Seethesuspensionmanufacturer’sspecicationsforloadversus
pressure.Verifythatthetrailer’sairsuspensionpressureis<130psi
andiswithintheallowablerangeforthespecicsuspension/airbag
combination.[below50%ofairbagpressureattheunladenweight,or
above50%ofairbagpressureatGVWRforaxles]
• After repairs — or if no issues are found — clear the diagnostic code.
• If the diagnostic code persists, contact the BCVS local representative
before replacing the TABS‑6 Adv MC module.

Internal Pressure
Sensor Range:
DeliveryPort“P21”
• Perform a Pressure Component Test using the Bendix
®
ACom
®
diagnosticsoftware(version6.1orhigher).
• Verify the trailer’s control (service) and brake delivery pressures are
comparableand<130psi.
• After repairs — or if no issues are found — clear the diagnostic code.
• If the diagnostic code persists, contact your local Bendix
representative before replacing the TABS‑6 Adv MC module.

062/12 1052/12
7 5
Internal Pressure
Sensor Range:
SupplyPort“P1”
•Verifythetrailer’sservicereservoirpressureis<123psi
(8.5bar).
• After repairs — or if no issues are found — clear the diagnostic code.
• If the diagnostic code persists, contact your local Bendix
representative before replacing the TABS‑6 Adv MC module.

LateralAccelerationSensor
8 1
LateralAcceleration
Sensor ‑ Signal
MountingError
• Before troubleshooting, verify that the trailer has been parked on
level ground.
•VerifythattheTABS-6AdvancedMCECUhasbeenprogrammed
withtheproperECUorientation,tiresizeandtoneringsettings.
• Verify that the TABS‑6 Advanced MC module has been mounted as
per the Installation Guidelines:
-TheconguredECUorientationmatchestheactualECU
orientation.
‑ Verify that all wheel speed sensors are installed correctly
(correct axle/left/right) (See Figure 19)
• 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 MC module.
