AQ964110
This is a Haldex ABS electronic control unit (ECU) upgrade kit for heavy-duty trailer anti-lock braking systems. It replaces older Haldex ABS controllers with the newer PLC Select platform, providing faster cycling, improved stability, and support for modern diagnostics via PLC and CAN communication. The kit is designed for 2-sensor/1-modulator (2S/1M) configurations and is typically used on tandem and multiple-axle trailers when upgrading a failed or outdated ECU to enhance braking performance and reliability.
Upgrade kit for older Haldex ECU models (AL40953, AL919302, AL919310). Pre-March 1998 modal systems are not directly interchangeable; contact Haldex for upgrade instructions. Haldex recommends replacing wheel-end sensors when upgrading.
