If your scan tool is pointing at the ECU — not a downstream sensor — we can fix it. These are the most common faults we see every day.
P06xx Fault Codes
P0600–P0606 codes mean the problem is inside the computer itself — not a sensor or wiring harness. These include internal processor errors, ROM/checksum faults, and CAN controller failures.
- ✓ All P06xx and P062x variants
- ✓ Checksum and ROM errors
Crank No-Start
Engine cranks normally but will not fire — and all sensors test within range. This pattern usually means the ECU is failing to send injector or ignition trigger signals due to an internal processor or driver failure.
- ✓ Board-level output driver testing
- ✓ Flash memory verification
U-Code CAN Communication Faults
U0100, U0073, and related codes indicate the ECU has dropped off the CAN network. When the ECU is the source node, it often signals a failed processor or power supply on the module itself.
- ✓ CAN transceiver testing & repair
- ✓ Power supply restoration
Water Damage & Corrosion
Flooded footwells, coolant leaks onto the PCM, and condensation cause corrosion damage that develops slowly. We clean, rework, and component-repair water-damaged boards — often saving units other shops declare totaled.
- ✓ Board cleaning & corrosion removal
- ✓ Bench-tested before return
Corrupted Flash / Failed Update
An interrupted programming session, a failed OBD update, or a voltage spike can corrupt the ECU’s software. We restore the factory calibration matched to your specific VIN.
- ✓ EEPROM read/write recovery
- ✓ VIN-matched OEM calibration
Failed Injector / Ignition Drivers
Power supply regulators, injector driver transistors, and ignition output chips are discrete components we replace on the board — not reasons to replace the entire ECU.
- ✓ Component-level SMD soldering
- ✓ Power rail diagnosis
What Component-Level Repair Actually Means
Most shops that offer “ECU repair” are reflashing the module or swapping it with a used unit. We repair the actual hardware — the individual capacitors, resistors, processor chips, and memory ICs on the circuit board.
A used replacement ECU still has to be programmed to your VIN and may carry its own hidden failures. Repairing your original unit preserves your VIN data and eliminates the root cause.
- ✓Original VIN data preserved — plug-and-play return in most cases
- ✓Root cause fixed — not masked by a used module with its own faults
- ✓Bench-tested under load before shipping back to you
- ✓12-month warranty — if it fails within the year, we fix it again free

ECU Repair FAQ
How do I know my ECU is the problem and not a sensor?
Fault codes in the P06xx range that point specifically to the ECU module (not peripheral sensors), U-code communication errors referencing the ECU, and no-start conditions where all sensors test fine are strong indicators. A scan tool pointing to the ECU module itself — not downstream components — is your clearest sign.
Will the repaired ECU be plug-and-play?
Yes. We program the ECU to your specific VIN and factory calibration before shipping it back. In most cases it is plug-and-play with no dealer visit needed. Some vehicles may require a brief idle relearn cycle after installation.
What if my ECU has water damage?
Water damage is repairable in many cases. We inspect the board, clean corrosion, replace damaged components, and retest on the bench. We’ll diagnose it and contact you with a repair assessment before proceeding.
How long does ECU repair take?
Most ECU repairs are completed in 48–72 business hours from receipt. Rush service is available — contact us when submitting your quote request. We ship the same day repair is completed.
What if you can’t fix my ECU?
If we cannot repair your ECU, we ship it back at no charge and issue a full refund. No fix, no fee. That’s our money-back guarantee.
What vehicles do you repair ECUs for?
All makes and models — Ford, Chevy/GM, Dodge/Chrysler, Toyota, Honda, Nissan, Hyundai/Kia, BMW, Mercedes-Benz, Audi, and more. Contact us if you’re unsure about your specific vehicle and module part number.
