Just purchased, Please HELP!

Postby adrians8 » Fri Nov 24, 2017 6:25 pm

Hello guys,
I recently purchased a 2007 G35x, did a pre-purchase check and a list of codes showed up. I purchased the car for $12k with just over 66,000 miles on it. Obviously I should have done some more research on the codes because after looking them up it looks like some are common and serious. Here is the list I have....

SRS System
-B1018 Occupant sensor (unit fail)

BCM
-B2014 Chain of steering lock BCM
-B2562 Low voltage
-B2607 Steering lock relay

Intelligent Cruise Control
-C1A14 ECM circuit
-C1a26 ECD Mode malfunction
-C1A04 ABS/TCS/VDC Circuit

IPDM
-U1000 CAN Communication Circuit
-B2099 ignition relay off
-B2109 Steering Lock Relay off

Stereo/Convenience
-U1300 Audio visual communication circuit
-U121F TBD control unit initialize

and "several tire pressure warning system codes present"

I took this exactly from the report given to me.

Now I understand U1000 is a big one that relates to a few of the other codes. I did some research and learned that in older cars the ground wiring might just be rusty causing the U1000. However I dont know what to look for besides the wire that connects to the negative. I would like to learn/fix as much of these as I can on my own, as I am a student with little extra funds. Thanks for your help!

As a student why would you spend $12k on a 11 year old vehicle without having the vehicle and its VIN number inspected by an Infiniti dealer to obtain a vehicle history?
Over 500,000 vehicles in the United States are flood vehicles and it sounds to me like you were played for a sucker and purchased one of them.

Return the vehicle and get your money back

Just my $.02

I purchased a Carfax before buying it and it came up clean, and was purchased and remained on the west coast.

Yeah, with the vehicle lighting up like a pinball machine something drastic had to have happened to it. Unfortunately you didn't walk away when you saw the codes prior to purchase as you overpaid for the vehicle and bought one that is a mess. Live and learn....

I would suggest going through the FSM for each code and begin troubleshooting. It may take a whole lotta time and patience to find everything wrong but having Infiniti do it will cost you BIG bux. Alternative is to find a local mechanics shop and see what they can do.

Here is a link to the FSM's http://www.nicoclub.com/archives/infini ... nuals.html

HI: Did you ever get to fix this? For what I see, you might not have all those problems at all but just the relays from the IPDM might be causing most of them. Infiniti/Nissan had problems in the past with the relays in the idpm, going from the maxima to the altima, G35,G37 etc. Mostly it is the same model relay used in several model cars. For example, the ignition and steering lock relay relays will give you a cascade of problem codes that will go away once you replace the relays, if that is the main problem. Some relays are chained to more than one system and then only way you can see this is in the schematic manual of your car. U1000 could be any relay that is bad, because the only thing it is telling you is that the can bus of one of the modules is not transmitting or receiving. Just for curiosity, let me know if you fixed it or we could go over the schematics and find a possible cause.Good luck.
