Diagnostics and Programming
Is a mystery dash light—or sudden loss of Bluetooth—ruining your commute? Our computer diagnostics & programming service zeroes in on software-related faults fast, so you get back to smooth, worry-free driving.
Computer Diagnostics & Programming Services in Grand Rapids, MI
Modern cars carry 30–50 separate control modules—everything from the ECM that times each spark to the body control computer that runs your power windows. Kleyn Auto keeps pace with that technology by pairing OEM-level scanners with factory software for Ford, GM, Chrysler and many imports. We retrieve live data, pinpoint corrupted code, and reflash or update modules before they fail. Typical symptoms we solve include:
- Check-engine or ABS lights that keep returning
- Infotainment freezes after smartphone updates
- Hard starts following a battery change
- Lane-keep or cruise-control glitches
Because our programming tools write new calibrations directly to your vehicle, you avoid unnecessary parts swaps and protect factory warranties.

What Does A Full Engine Diagnostic Include?
A complete diagnostic starts with an all-module scan to capture current, pending, and historical fault codes. Technicians then verify live data—fuel-trim, sensor voltages, misfire counters—and perform targeted tests such as smoke-leak checks or oscilloscope waveform analysis. Finally, a road test confirms normal operation before clearing codes and documenting results.
Can Fault Codes Be Read If The Check-Engine Light Is Off?
Yes. Control modules store “pending” or history faults even after the light extinguishes. Reading them early lets us catch loose connectors, low-voltage events, or intermittent misfires before they grow into expensive breakdowns. Early detection saves you time, money, and the hassle of roadside surprises.
