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
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).
