Toyota ECU Repair FAQ
Why do Toyota ECUs fail?
Toyota ECUs are generally reliable but fail for several known reasons: water intrusion through firewall grommets (especially on Tacoma and Tundra), capacitor degradation on higher-mileage units, voltage spikes from jump-starting, and connector corrosion. The ECU is repairable in the vast majority of cases — we identify and fix the root cause rather than replacing the entire unit.
Will my Toyota keys still work after the ECU repair?
Yes. We re-register your existing transponder keys to the ECU during programming. On most Toyota platforms this is seamless and your keys work normally after reinstallation. If you’ve lost all keys, we can perform an all-keys-lost procedure via EEPROM — contact us with your year, make, and model to confirm.
Can you repair Toyota hybrid ECUs?
We handle standard ECU and TCM repair on Toyota hybrid platforms (Camry Hybrid, RAV4 Hybrid, Highlander Hybrid). Contact us with your specific hybrid model and fault codes — some high-voltage components are outside scope, but most standard ECU faults on hybrids are repairable.
How long does Toyota ECU repair take?
Most repairs complete in 48–72 business hours from receipt. Rush 24-hour service is available for an additional $75–$100.
What if you can’t fix my Toyota ECU?
We ship it back at no charge and issue a full refund. No fix, no fee — no exceptions.
