KALMAR issued a recall on multiple vehicle models

On certain terminal tractors, the electrical wiring to the Anti-Lock Brake System (ABS) modulator valves from the Electronic Control Module (ECM) is incorrect. The wires to the "Exhaust" and "Hold" connections on the ABS modulator valves are reversed. In an anti-lock braking event, this will cause the ABS to malfunction. ABS performance will be degraded, increasing the risk of a crash. Correction: Dealers will install 4 modulator valve jumper harnesses.
