OEM Mitsubishi Lancer CJ ABS Pump Control Module Actuator Part No. 4670A265 (2007-2013)

No, but it does require calibration. Unlike European vehicles or newer Mazda systems, the electronic module on the Lancer CJ 4670A265 is generally plug-and-play regarding the engine immobiliser and VIN matching. However, once bolted in, you must use a diagnostic scan tool (such as a Mitsubishi MUT-III or a high-end scanner like a Launch or Autel) to perform a Steering Angle Sensor (SAS) Calibration and a Lateral G-Sensor Calibration. Failing to calibrate these sensors will cause the ASC (Active Stability Control) light to stay on even if the pump motor fault is fixed.

These two codes are the absolute "death sentence" for the factory ATE MK70 unit installed in 2007–2013 Lancers: 1. C2116 (Pump Motor Supply Voltage Low): Indicates the internal electric motor brushes have worn down or seized, preventing the pump from building hydraulic pressure. 2. C1073 (ABS Pump Motor Circuit Malfunction): Points to a failure in the internal relay circuit on the electronic board or a completely dead motor. Because these are internal mechanical and hardware failures, clearing the codes with a basic OBD2 scanner will not work. The entire physical assembly must be replaced.

While some DIYers attempt to separate the electronic module from the hydraulic aluminum block to avoid bleeding the brakes, we highly advise against it. The internal solenoids on the 4670A265 seat into the hydraulic valves with precision factory seals. Separating them on a dusty workbench often introduces contaminants into the valve block or breaks the delicate internal ribbon connections. Replacing the complete assembly—both block and module together as a matched unit—is the only way to guarantee your braking system performs safely in an emergency stop.
