Most of the time when your code says no bus there is a loose wire or conector between the ecm and the dash,
Many times its where the wireend conects to the speedo head where it is a problom. I would look there first

2006 jeep liberty has transmission problem at 40 mph. What are computer codes p0700 and v0002

dash display not scanned, you for got to say? or how you scanned with what, if did.
A/T is a very expensive and complex beast. no person can guess this. what transmission which engine? they are a match.
V6 gas and Diesel for 2006 are the 2 options and 2wd and 4wd.
we need the tranny name. RFE name.
700 vary be year and tranny.
there are 2 issues, here, the sensor reads wrong because the sensor is bad (or contaminated) or the tranny slip.s
testing solves this, issue.

the tech reads the FSM for your car, then sees which tests are first
for P0700.
you never said the problem, (driving)
some jeeps have 2 transmission options, even 2wd.
gas or diesel, another transmission.

ill tell you what the FSM says. about 700
it means that there are factory DTC codes , 700 is just a flag
IM SICK SCAN me with a REAL scan too. for JEEPs.
i use innova 3160, that sees all jeep codes.
here is the quote.
"This is an informational DTC letting you know that a DTC(s) is stored in the Transmission Control Module."
that V0002 is wrong, its "U" uniform code. not V.
U0002-CAN C Bus Off Performance this is communications error on the CANBUS.
"A module detects a short in either CAN C Bus circuit."

That bus is a NEWORK link.
the master on the bus sends command for many things.
and if the command is IGNORED< BAM, and error.
it means
1: command not received by X
2: or command never was acknowledged from X.

sounds like you need to get this jeep serviced.
id reset them all and pray it dont come back. (oldest story on earth)

2006 Chrysler 300, obd code u1120

U1120 means the PCM doesn't receive a vehicle speed signal from the Anti-lock brake Module over the CAN C bus. This can be caused by the ABS module, PCM or something wrong with the can bus. This might be just an erroneous code and may never set again.

No bus

have you reset the cpu to adjust it to the new sensors. Did you use genuine sensors as the cpu will not always recognise aftermarket units and reads them as faulty

My 2001 cherokee will not start. the engine will turn over. the voltage is good but it reads nothing on the gauge, neither will the fuel. after a few seconds the odometer will read "no bus"

Hi, the no BUS is usually a seriuos issue with engine controller communication. Can you check and see what trouble code is stored in the PCM (engine comuter)? This code needs to be retrieved with a code reader available at most auto stores for around $40. If you can give me the code, I can tell you exactly what is wrong and what will be needed to repair your Jeep.

1999 dodge durango stalls and a code that reads (no bus)shows up in the odometer what does this mean

try unplugging the crank sensor that is located in the bell housing of the transmission,on top of the bell housing,when these go bad they pull everything to ground including the bus communication,if you unplug it and the message goes away,replace the sensor,hope this helps

Engine shut down while driving

This will need a good repair shop , not necessarily a dealer. Find one recommended by friends that can do computer/electrical work. The "no bus" means the cars computer network is losing comminication between itself. This is not a code , but you might have code(s) stored in the computer system.A repair shop can scan for any stored codes to start the diagnosis.The problem could be in the PCM (engine computer) or even the Theft deterent system. Sounds more like theft deterent because of the no crank situation. If you have the spare ignition key try it & see if anything changes.
