If you are attending a Fiat 500 with a Marrelli ECU you must check for Neutral position switch fault using Kess 3 OBD Tool function (gear selection test/learn) - In the instructions on this protocol.

If a modified map is fitted with a fault the vehicle will require a trip to Fiat for it to be relearnt. £90-£150

Autotuner is now NOT an option to use due to the relearn procedure, with Autel no longer being in sub it won't let you carry out Clutch relearn, Neutral relearn or Phonics wheel relearn.

In some cases it shows ok for test but fails to load mod file. Do not try again refund required.

Abath 959/969 1.4T-jet is ok unless relearn is shown.

Kess 3 OBD only
