Diagnostic Trouble Codes
WHEEL SPEED SENSORS (WSS)
Display Odometer Mileage
To display the trailer odometer mileage, apply ignition
power and depress / release the brake pedal 7 times within
15 seconds. Following activation, there will be a 5-second
delay followed by a blink code display of the odometer
information (x1000).
Example: 152,431 miles will be displayed as: 152 (x1000)
or 1 blink (pause), 5 blinks (pause), 2 blinks.
Zeros will be displayed by the ABS indicator lamp strobing
twice.
Odometer mileage cannot be altered with blink code
diagnostics. Complete odometer information can be
retrieved using a diagnostic tool.
Resetting ABS Configuration
To reset the ABS configuration to the default configuration,
apply ignition power and depress / release the brake
pedal 8 times within 15 seconds. Following activation,
the TABS-6 ABS configuration will reset to the default ABS
configuration (2S/1M).
Repair Information
• ABS system fully operational – no faults detected
Dynamic Wheel Speed Sensor Fault.
Go to Section G, on Page 29.
Static Wheel Speed Sensor Fault.
Go to Section G, on Page 29.
• Verify correct tire size as desired.
• Verify proper tire inflation.
• Verify correct number of exciter ring teeth.
• Verify that the ECU has the proper tire size settings.
• Verify correct ABS configuration using blink codes
or other diagnostic tools.
• If needed, reset to the default ABS configuration and
power-up to initiate auto-configuration.
