Module Testing

Is it really the module?

Modules get blamed for a lot of problems that turn out to be wiring, power or ground. A bench test tells you for sure before you spend money on a new one.

What we check

A full workout on the bench.

Power & Ground

The module powers up and draws the current it should.

Communication

It talks on the vehicle network and responds to a scan tool.

Data & Software

Memory reads cleanly and the software and configuration are intact.

Inputs & Outputs

Circuits are exercised to find failed drivers and inputs.

Fault Codes

Stored codes are read and checked against the test results.

Written Result

You get a clear pass or fail, what failed, and what to do next.

How it works

Simple, start to finish.

Request a test

Tell us the vehicle, module and symptoms.

Ship it in

Full bench test with the results written up.

Your call

Ship it back, have it repaired, or replace it with a tested one.

Already tested

Every module we sell is tested too.

The same bench test is run on every used module before it ships, so you know what you're getting.

Shop Modules

Used, refurbished or aftermarket module? Contact us first. Not every module can be serviced, and some need extra equipment or time, which can add to the cost. We'll tell you before any work starts.
