I just hooked up my Launch X431 and got these codes: Right Bank Engine- U0029 Bus A Performance Malfunction P1059 Vehicle Speed Signal P0464 Fuel Level Sensor "A" Circuit Intermittent Left Engine Bank- U0142 No Comm. With Nbc P2069 Fuel Level Sensor "B" Circuit Intermittent Low Suspension Module Sachs Skyhook- U1706 No Comm. With NFR The car runs great and there is no CEL. Anyone tell me what these mean and how to fix them? I looked on the codes list in another post, and they are not listed. It's a 2009 F430. Sent from my iPad using FerrariChat.com mobile app
Most look like a low battery condition on start or otherwise Did you have a dead or weak battery ..was it replaced? If car is running fine ..print out .. reset dtc and check again in 50 miles or so Sent from my moto g(7) using Tapatalk
I bought the car in February and just bought the Launch for doing maintenance and F1 flushing. It’s been on a trickle charger the whole time, when I’m not driving it. I’ve got a battery load tester I can use to check the battery. Why do you think it’s a low battery? Do those codes indicate a low battery? Sorry, I’m still learning about the car and want to learn everything I can Sent from my iPhone using FerrariChat.com mobile app
If battery is good now and you keep it charged ..it might have been before the new battery was put in by PO .. How old is battery ? In most modern cars when you have a weak or low battery especially when starting you get a lot of communication errors which you have I would print them out ..reset and monitor Sent from my moto g(7) using Tapatalk
I’ll have to check on the battery date. It’s a red Optima and was in the car when I bought it, so I don’t know how old it is. The car starts very quickly every time, and the trickle charger shows “charged” shortly after plugging it in. Sent from my iPhone using FerrariChat.com mobile app
Ok if more than 5 years it may be questionable .. but from what you tell me it may have been replaced by PO .. I would monitor after reset and let me know if battery tester shows "good" Sent from my moto g(7) using Tapatalk
Just did a load test on the battery. It shows in the “green”, but at the lower portion of it. I haven’t driven the car in 2 weeks, but it’s been on the trickle charger. I can’t see the date on the battery while it’s in the car. It’s a red Optima 34R. I’ll start shopping for a new battery and reset the codes and see what happens. My main concern was that I’m not doing any damage to the car by driving it. Sent from my iPhone using FerrariChat.com mobile app
The codes may just be history codes that were never cleared by the technician. If you have the Launch Tech USA you can save the codes, clear them, drive the car, and read the codes again. If you don't see them repeated you're good to go. Ray
Hi guys, I have error U1706 in my 2009 F430 spider F1, do you have solve it? Thank you! Marcello Enviado desde mi SM-N986B mediante Tapatalk
Have a look on Amazon for a volt meter that plugs into the power socket between the seats. When you press start, see how far the volts drop when the starter engages. If the battery is getting past its best the volts will drop too much and you get all sorts of codes. This voltmeter is very small so you can put in the glove box if not in use but handy to carry
Wondering if you found out what caused the codes. I have the exact same codes on my car, and the car runs perfectly fine. Came across this thread, so I bought a new battery since it's been 5 years since i owned the car, i was shocked to find the old battery to be 11 years old and working fine. Put new battery in, no difference. Try to clear the codes and they persisted, even though a lot of other misc. codes went away (suspension, gearbox, abs etc, i had a feeling those were voltage related since they only came up recently as I scan the car a lot more)
I suspect those codes are not real codes. I don’t know what else to say. I have looked into 3 F430 and all of them have similar codes including mine, but run fine.
