Standard Motor Products LX729 Ignition Control Module

The Standard Motor Products LX729 is a precision-engineered ignition control module designed to restore reliable engine operation. This solid-state electronic component controls the operation of the ignition coil, acting as a high-current switching device that grounds the negative side of the coil to build charge and regulate base ignition timing.

Key Features:

• Direct replacement for OEM ignition control modules on select Mitsubishi, Dodge, Chrysler, and Plymouth vehicles
• Engineered to meet or exceed OE specifications for fit, form, and function
• Solid-state design ensures accurate, maintenance-free operation
• Controls ignition coil operation for precise spark timing
• Heat-resistant construction to prevent premature failure
• Intermotor brand quality from Standard Motor Products

This module receives signals from the engine management system and relays them to the ignition coil, determining charge time and spark firing. Cross-references to OEM numbers MD152999, MD160535, MD304018, and J723T. When ignition control modules fail, the most common symptom is a no-start condition, though failing modules may also cause engine stuttering or stalling.
