Detailed Product Overview

Standard Ignition MC2201 is engineered for starter relay service where consistent current control matters. The relay’s aluminum contact design supports long-term electrical performance, while the composite housing and epoxy protection help it hold up in severe under-hood environments. Manufactured in TS16949 and ISO9001 certified facilities, this relay reflects controlled production standards for automotive electrical repair.

This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application. When replacing a worn relay in Honda Civic or Toyota Corolla electrical systems, MC2201 offers a practical option for restoring starter circuit operation and related relay-controlled functions.

Common Problems This Relay Can Help Solve

• No-start condition caused by a failed starter relay
• Intermittent starter engagement or delayed cranking
• Electrical switching issues in relay-controlled circuits
• Heat- or moisture-related relay failure in the engine bay
• Coolant fan relay malfunction in applicable vehicle systems

Installation Notes and Tips

Verify the connector shape, terminal count, and voltage before installation. Match the 5-blade terminal layout and mounting bracket style to the original relay location. Inspect the relay socket, terminals, and surrounding wiring for corrosion, heat damage, or looseness before installing MC2201. For fitment-based searches, confirm the vehicle application against the original part number and electrical configuration on the Honda Civic or Toyota Corolla.
