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.

Load Port “P42”
• See the suspension manufacturer’s specifications for load versus
pressure. Verify that the trailer’s air suspension pressure is <130 psi
and is within the allowable range for the specific 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.

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.

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 configured 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.
