Standard Ignition LX-1117 Ignition Control Module

Ignition Control Module for Mercedes-Benz 380SEL

Standard Ignition LX-1117 is an ignition control module built for 1981 Mercedes-Benz 380SEL, 380SL, and 380SLC applications. It is engineered for stable coil control, dependable signal response, and improved resistance to heat, vibration, and moisture in demanding underhood conditions.

Key Features

• Bolt-on attachment with a male connector layout
• 2 connectors, 5 blade terminals, and 12-volt operation
• Fender-mounted design for the listed Mercedes-Benz applications
• Double wire bonds for stronger electrical connections and longer service life
• Copper slug heat sinks to improve heat dissipation
• High-temperature polymer housing to reduce moisture intrusion and vibration damage
• Responds to weak crankshaft position sensor signals for quicker coil energizing in cold starts
• Durability tested through 500 thermal cycles from -40C to +125C

Detailed Description

Standard Ignition LX-1117 is a direct-fit ignition control module for 1981 Mercedes-Benz 380SEL, 380SL, and 380SLC models with fender-mounted ignition module placement. It is designed to manage ignition coil operation with reliable signal handling, especially when the original module has failed from heat cycling, vibration, or moisture exposure. The module’s internal construction focuses on electrical stability and thermal control, which supports consistent ignition performance in older Mercedes-Benz systems.

This part cross-references Bosch 0227100001 and Mercedes-Benz 0005457632 for the same application. Standard Ignition LX-1117 is a practical replacement choice when servicing a 1981 Mercedes-Benz 380SEL ignition control module, a 1981 Mercedes-Benz 380SL ignition control module, or a 1981 Mercedes-Benz 380SLC ignition control module.

Common Issues This Part May Solve

• No-start or hard-start conditions related to ignition module failure
• Intermittent spark loss during engine operation
• Poor cold-weather starting caused by delayed coil energizing
• Heat-related ignition breakdown from repeated thermal cycling
• Moisture- or vibration-related module damage

Installation Notes and Tips

Verify the connector style, terminal count, and fender-mounted location before installation. Inspect the crankshaft position sensor signal, wiring condition, and coil connections during diagnosis, since ignition module faults often appear alongside damaged connectors or heat-affected harnesses. Confirm the vehicle is a 1981 Mercedes-Benz 380SEL, 380SL, or 380SLC before ordering LX-1117.

Quality Assurance

Standard Ignition manufactures electronic ignition components with in-process quality control from component selection through final assembly. LX-1117 is built with heat management and vibration resistance features intended to address common failure points in ignition control modules.
