Freightliner: ABS fault codes due to connector water intrusion

Bulletin number

SB-42-63

Component

Service brakes, air: antilock: ABS warning light

Summary

Freightliner: ABS fault codes due to connector water intrusion. On some trucks, the ABS module was moved into the cab. This required a connector to be placed under the cab, behind the front steering axle, on the frame rail. If this connector is loose, or improperly installed, moisture can enter the connector and cause corrosion on the terminals, which will lead to connectivity issues, causing various ABS fault codes, and the ABS dash light to come on.
