Abs module light on international truck.

Depending on the abs system should be wabco you will need to plug into it to find the problem. It s not uncommon for the abs light to come on with many trucks. This bendix tech talk discusses what steps to take when a commercial vehicle s dashboard abs anti lock braking system warning lamp is activated. Sometimes it s just dirt or rust particles on the exciter ring inside the drum.

If the abs system is damaged the problem is usually found in the wiring. Behind the wheels on the brake rotor assembly there will be two wires running to the back of the brake rotor. I have a international 4300 2004 abs light on with code for driver side drive sensor i put 2 sensors on a checked wiring. These are the abs sensor wires.

This morning while driving the truck went over a bridge expander bump and now i am getting two errors. Many trucks will have this light illuminated to simply tell you that the trailer they are towing does not have abs. Make sure that none of the wires is damaged. Check the abs sensors at the wheels.

The lights and notice come on then go off for a few minutes then back on again. Look for pinched broken loose wires on the wheel sensors and check the air gap between the sensor and excitor ring on each wheel. Also check to see if all 4 sensors are pushed in all the way. I have an international 4300 and the electric fault and abs module is on.

1 service anti lock braking system with the abs light on. Do they have any abs software. Check the connections at the main abs relay valve and modulator valves if the system has remote ones. It will give you fault codes and data monitor.

Check the fuse for the abs. Some will allways be on until an abs trailer is plugged in at the rear. Being a international they are known for the tone rings on the rotors for the abs to rust bad enough not to pick up a signal. It does sound strange it is intermittent tho.
