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:
• 1.10: Radar Sensor Interchangeability
• 4.6: J1939 Serial Data Communications Link
• 4.7: J1939 Engine Communications Test Procedure
• 4.7.1: J1939 Troubleshooting Procedure
• 4.8: Troubleshooting Wiring Harnesses
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 devices inhibiting J1939
communications.
• With the power off, check the resistance across connector
pins (60 ohm).
• Check the reverse polarity of J1939 communication circuits
at the engine, the ABS and the radar 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 radar 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 ® Advanced ™ system diagnostic
trouble codes using the procedure in Section 4.4: Clearing
Diagnostic Trouble Codes (DTCs).
• If the error returns, call the Bendix Tech Team for assistance
at 1-800-AIR-BRAKE.
156 - ABS off-road switch is turned on
Perform the following:
Check engine, and engine retarder trouble codes.
Inspect and troubleshoot the cruise control system wiring,
switches, etc. for proper operation.
• Clear the Wingman Advanced DTCs using the procedure in
Section 4.4: Clearing Diagnostic Trouble Codes (DTCs).
• If the error returns, call the Bendix Tech Team for assistance
at 1-800-AIR-BRAKE.
NOTE: Wingman Advanced is disabled when the ABS off-road
switch is ON. However, the engine cruise control may still
operate. This DTC will result in the engine cruise control being
de-activated.
