ACB TROUBLESHOOTING CODES (CONTINUED)
Actions
Possible causes:
• J1939 missing signal on the communication link, or
the source of the signal is indicating an error in the
signal.
Review the following sections:
• SENSOR INTERCHANGEABILITY
• J1939 SERIAL DATA COMMUNICATIONS LINK
• J1939 ENGINE COMMUNICATIONS TEST
PROCEDURE
• J1939 TROUBLESHOOTING PROCEDURE
• TROUBLESHOOTING WIRING HARNESS
Perform the following:
• Check for loss of data communications.
• Check for damaged or reversed J1939 wiring.
• Check for damaged or corroded connectors.
• Check for other
communications.
• With the power off, check the resistance across
connector pins (60 ohm).
• Check the reverse polarity of J1939 communication
circuits at engine, ABS, and ACB sensor, and at the
harness interconnections.
• Check the source of the signal to identify why the
signal has an error.
• Check the engine, engine retarder, and ABS for trouble
codes using the manufacturer's diagnostic procedures.
Either the engine, engine retarder, or the ABS are
the source of the signal. If the signal is in error, then
the issue is from the sensor or switch input to one of
these controllers. The signal with the trouble code
may be computed from one or more inputs to these
other controllers and may use an additional J1939
signal from another controller. The controller that
broadcasts the signal must be investigated fi rst, but
the origin of the signal could be another component.
Some examples are gross vehicle weight and various
engine torque signals.
• Clear the Bendix ® Wingman
the procedure CLEARING BENDIX
ACB DIAGNOSTIC TROUBLE CODES (DTC).
• If the error returns, call the Bendix Tech Team for
assistance at 1-800-AIR-BRAKE.
Possible causes:
• One or more components within the Bendix
ABS or ESP ® stability system have active trouble
codes that need to be diagnosed and corrected.
Perform the following:
• Inspect brake mechanical and pneumatic system for
proper operation. Correct the issues found in the
Bendix ® ABS or ESP
codes before proceeding to the ACB system.
• Clear the Bendix ® Wingman
