Good day! Have Suzuki Grand Vitara 2001, 2.6 Last week while at a traffic light, it shut down. Put the car in Parking, re-started and it it worked normally. Today I push the break pedal as a car suddenly stopped and it power down again, but then it starts with no problem. The one thing I noticed, is that the radio resets.. like it was getting no power so it takes the clock to 0 and it looses all the set stations etc... Any ideas?
I cant drive it and see the obvious
seem like total loss of battery power to cab and engine EFI systems
that is called an engine stall,
if the cars cab power goes dead, (sorry no RADIO made can do that) then you notice the cluster reads funny, (dead things)
head lights dim or out ,stalled.
the GV has dash tachometer, if you look at it RPM is 0 at stalls
the CEL lamp glows and others with it. (this is the key on self check doing the lamp tests)
if the lamps are dead, and all meters go to zero
that is lost power, lost 12vdc battery power to the cab.
(and other places too.)
so the battery cables are green with corrosion. clean them yet>?
my guess, is car is 01 GV with H25, 2.5L V6 engine,
with the automatic and not the stick shift.
learn to watch that TACHometer gauge.
0 rpm is stalled
800 is normal RPM in park or DRIVE. (foot off gas pedal)
if rpm is 400, that is gross missing (all cars not tuned up do that)
see? and when a car stalls
the brakes act weak (vacuum ends, and does)
and steering is harder to turn, PS assist is dead, all normal for stalls.
the question is what causes the stalls, there are over 50 reasons
im not going to list all 50 nor the up to 10 tests to find it.
why not get car serviced, ?
if that is not possible say so, and we can do the tests.
after you buy tools
got money for tools or is this just I want someone to guess deal.?
clock to 0 tell me the most here.
tells me total loss of battery power. !
the clock is wired to battery hot all time feed. (so you can sleep and clock dont forget its count)
and if it resets that means that feed went to 0v. zero volts.(or near)
and most times, that is green battery lugs."corrosion from acid"
lead oxide turns green.
those lugs are checked at every car service.
tells me , you never get this car serviced at least 1 time per year.
is this correct?
The first thing that comes to mind for the radio is loose wiring. You didn't mention whether it was aftermarket or stock? You might want to check whether any trouble codes have been stored for the engine stalling issue.
Testimonial: "Aftermarket but it only happens when the car shuts down, not all the time... Radio has been working fine for 4 months now since it was installed but when the shut down issue started, so did the radio problem"
Ok, I think I see the problem with the radio. Nice job providing information by the way. If everyone at fixya gave details like you, they would get better help.
The radio has separate power wires. One of them is red and normally shuts on and off with the key to shut your radio off when you turn the car off. The other is yellow and needs to have power all of the time. Even when the car is off. It's called a memory wire. This is what keeps your clock and station settings intact. That yellow wire must be connected to a circuit that is shutting down when your vehicle stalls out. This can be corrected by wiring that yellow wire to a different full time power source. (it won't consume a ton of power and run your battery down)
I don't know if your used a harness or cut your factory wiring to interface with your aftermarket radio?
Alternatively, when you fix the stall issue, the radio issue should be fixed as well if you don't feel like re wiring that yellow power feed.
