Ignition Control Module LX – 19017161, 1U2Z12A297AA, 1U2Z12A297AB, 81SF12297FB

This ignition control module is the electronic switch that tells the ignition coil when to fire. The supplier lists it under four reference numbers, 19017161, 1U2Z12A297AA, 1U2Z12A297AB and 81SF12297FB, and gives its size as 23 x 10 x 5 cm. Easy Life Markets sells it as a single module for owners and workshops who have traced a no-spark or stalling fault back to this part and have matched one of those numbers.

On engines that use a separate module, the job is split in two. The coil makes the high voltage, and the module decides the moment. It takes a timing signal from a sensor in the distributor or on the engine, switches the coil's primary circuit on and off, and so sets when each spark happens. Because it switches a heavy current many times a second, it runs warm, and heat is what usually finishes it off. A module that works cold and cuts out hot is a classic fault. There is a useful overview of how the pieces fit together in the ignition system article.

What Is Included

1 x ignition control module

Nothing else is listed. Mounting screws, a heat sink, connectors and heat-transfer compound are not part of the supplier's packing list, so plan to reuse your existing hardware.

How to Confirm It Matches Your Vehicle

We want to be straightforward here. The supplier does not name a single make, model or year. All it gives is "suitable for automobiles" and the four reference numbers. So the numbers are the only reliable way to buy this part:

Find the number on your old module. It is usually printed or stamped on the body. Compare it with 19017161, 1U2Z12A297AA, 1U2Z12A297AB and 81SF12297FB.
Look the number up. Put your old part number, or your VIN, into a parts catalogue and see whether it cross-references to one of the four above.
Compare the housing. Your module should have the same layout as the photo: a rectangular body, a plug at each end, four mounting holes and the "UP" arrow.
Count the pins. Check that the number and arrangement of terminals in each plug match your vehicle's wiring connectors.

If your old module carries a different number, please do not assume this one will work. Send us the number and a photo and we will compare it with the supplier's listing for you.

Symptoms of a Failing Module

The engine cuts out when hot and restarts after cooling for twenty minutes or so
The engine cranks but there is no spark at any plug
Intermittent stalling at idle or when coming to a stop
Misfires and hesitation that come and go with engine temperature
A tachometer needle that drops to zero while the engine is still turning

These symptoms overlap with a bad coil, a failed pickup sensor and poor wiring. Many parts stores and workshops can bench-test a module. Testing first can save you buying a part you do not need.

Installation Notes

Disconnect the battery negative terminal before you touch any ignition wiring.
Note which plug goes to which end of the module, or take a photo, before unplugging.
Mount the new module with the "UP" arrow pointing the way the old one did.
If your original module sat on a metal plate or heat sink with a layer of heat-transfer compound, clean the old compound off and apply a fresh thin layer. A module that cannot pass its heat into the mounting surface will overheat.
Make sure the mounting surface is clean bare metal where the original used it as an earth.
Check the wiring plugs for green corrosion or bent terminals and clean them before reconnecting.

If you are not confident with electrical diagnosis, ask a qualified mechanic or auto electrician to fit and test the part.

Why Modules Fail and How to Protect the New One

Heat and voltage are the two enemies. A coil with shorted windings draws more current than the module was built to switch, and it can take out a new module within weeks. Before fitting this one, it is worth measuring the coil's primary resistance against the figure in your service manual, and checking that the charging system is not overcharging. Worn spark plugs and leads raise the load on the whole ignition circuit too. Fix the cause and the replacement has a fair chance of lasting.

Who This Part Is For

Owners, restorers and garages working on vehicles that use a separate ignition module with one of the four listed numbers. It is not a universal part, and it is not the right choice if you have not been able to match a number.

Common Questions

Which cars does it suit? The supplier does not say. It lists reference numbers only, so please match 19017161, 1U2Z12A297AA, 1U2Z12A297AB or 81SF12297FB against your old part.

Is it a genuine part from a vehicle maker? No. This is an unbranded aftermarket module. The numbers are there for cross-reference.

What does "LX" in the name mean? It is part of the supplier's product name. The supplier does not explain it, so we do not treat it as a fitment detail.
