Optional Automatic Traction Control (ATC): • Helps you accelerate on slippery surfaces and reduce drive wheel overspin. • The ATC indicator lamp is marked ATC, ASR or Wheel Spin (depends on vehicle make/model). • Some vehicles without ATC have a Wheel Spin lamp to show if drive wheels are spinning. • The blink code diagnostic switch must be off (if equipped in vehicle). Vehicle is in operation The ATC lamp should only come on when a wheel is spinning. If it comes on during normal vehicle operation, or if it does not come on when a wheel is spinning, there is a malfunction and your vehicle should be serviced as soon as possible. You’ll still have ABS brakes, but without ATC.

ABS helps prevent wheel lock-up during braking to increase vehicle stability and driver control.
How to Brake with ABS Do what good drivers have always been doing; brake just the way you always have — Apply brakes as normal to stop in time. When your ABS starts working, don’t release your brakes — maintain brake pressure.
ABS for Tractors, Trucks and Buses
Trailer ABS
• The blink code diagnostic switch must be off (if equipped in vehicle). Turn on vehicle ignition
Turn on vehicle ignition
If driving with a single trailer, doubles or triples… Watch your trailer(s) through your mirrors and correct brake pressure as necessary to keep in a straight line. If only your tractor has ABS… Use your rig’s brakes as necessary to straighten out your trailer if it swings out. Watch the trailer through your mirrors to make sure it follows your tractor properly.
Begin to drive the vehicle The ABS warning lamp does not go off
No
Does the ABS warning lamp in the cab come on and go off?
Yes
System is OK
If only your trailer has ABS… Use your rig’s brakes as necessary to maintain control and keep your combination in its lane.
Yes
If driving a straight truck or bus... Maintain continuous pressure on your brake pedal while steering clear of any obstacles.
If your vehicle is being towed — Disconnect the ECU or pull the ABS fuse.
No
Begin to drive the vehicle If the lamp comes on above 4 mph, or if it remains on during the entire braking application, there is a malfunction. Your vehicle should be serviced as soon as possible after completing the trip.
Avoid rapid “pumping” of the brakes — During a brake application that could result in a wheel lock, Meritor WABCO ABS automatically releases and applies the brakes up to five times per second, obviously much faster than you could do pumping the brake pedal. Always remember that you are the most important element in the safe operation of your vehicle — ABS is not an excuse to take unnecessary risks. Always drive carefully and stay a safe distance away from the vehicle in front of you.
Does the trailermounted ABS warning lamp come on above 4 mph or come on and stay on during the entire braking application?
No
Does the lamp go off as vehicle reaches about 4 mph (6 km/h)?
Yes
System is OK
Note: Depending how the ABS is powered, the lamp may come on briefly at ignition and then go off, or briefly flash each time you apply the brakes on a moving vehicle. If the lamp stays on, have your vehicle serviced as soon as possible after completing the trip. There is a malfunction. Only the ABS in the affected wheel(s) is disabled; that wheel(s) then has normal brakes.
System is OK
