ABS BRAKING SYSTEM
As of 3/1/98 all trailers manufactured with air braking systems are required to have an ABS (Anti-Lock Braking
System).
The system used on your trailer meets or exceeds the FMVSS 121 requirement for ABS. The ABS system on
your Bulk Commodity trailer is a 4S/2M system (4 wheel sensors - 2 modulator valves) or a 2S/1M (2 wheel sensors
- 1 modulator valve). The intended purpose of ABS is to help maintain control and reduce the likelihood of jackknife
situations.
The ABS status indicator light is located on the driver side of the trailer near the rear corner post. It indicates the
system status upon initial startup by turning on and then turning off once the vehicle begins to move. If a malfunction
in the ABS system occurs, the ABS system status light will come on and stay on until the problem is repaired. Anytime
the system status light comes on and stays on, have the ABS system serviced as soon as possible.
WARNING! ABS (Anti-Lock Braking System) is a safety item and must be
properly maintained. To operate an ABS equipped truck and trailer properly, during
braking- constant pedal force must be applied. All ABS systems require clean, dry
air to operate properly. Use of airline deicers or leakage of oil into the air system
may diminish the performance of the system and will void the warranty.
BACKUP WARNING SYSTEM
A backup warning system consisting of an audible alarm is available as an option on your Timpte Bulk Commodity
trailer. The system is intended to indicate that the vehicle is backing up.
