G35 electrical problems ?

[Natacha025]

Hi guys I'm new here and wanted to see if any of you have experienced this
with their 2003 g35 coupe. My hubby recently bought a used 2003 g35 coupe with 101000 miles
everything was working fine except i had a couple suspension and direction
repairs to do, he got those done in the last couple weeks but about three
days ago at start up he would get 3 lights on the dash board and a rough idle.
Lights were abs, slip , Vdc off. After waiting about 5 mins the light would turn
off the rpm would go back to normal and could drive all day and be fine. Now
they other problem that just happend is the heater/ac would turn on full blast
can't turn it off and radio as well. Has anybody had that problem that could
save me a couple bucks ? I've already put a lot of money in the past month in
repairs and don't feel like paying another 1-2000
Repairs recently done
I've changed.. Rack and pinion Upper and lower control arms Tie rods Ball joints Rear break pads Rear wheel bearings Changed my headlights

I know many members here say the Infinitis are finicky about electrical power. Do you have a spare battery you can try?

Unfortunately no..

Usually the 3 lights (abs, slip , Vdc ) coming on are an indication that you need to look at the brakes (either the pads need replacing or the fluid is low), but, they can also indicate an issue with cam or speed sensors. Brake issues should not cause the RPM issue so I would look at the Cam sensors or speed sensors as the culprit.

I forgot to mention that when at start up with the three lights on Vdc, slip and abs even if I press on the gas there is nothing happening I could only put it in reverse and back up but if I put it back in drive it does nothing at all until the light come off about 5 minutes later

Hmmm....I'd have a look at the TCM (transmission control module) as well.
