Have a question?
When fitting injectors to the newer Hilux / Prado models ( part number 295050-0460 ), you may see a fault code of P1601 after coding the injectors to the ECU.
The Baileys R & D team have determined that this is due to these vehicle models having a function called Pilot Quantity Learning , where the ECU can self-learn (forced) the pilot injection quantities, and stores this data in conjunction with the code.
This error arises because you’ve now changed the code, the ECU knows that post-factory injectors have been installed, and is detecting a conflict in the stored ‘learned’ values.

Interesting Fact:
The Pilot Learning function can in effect ‘recode’ the injector in-situ, and it’s our recommendation that this is completed every 40,000kms and a standard part of the servicing checklist for your vehicle.
