U must have a shop test for the codes that are stored in memory, u can do this yourself if you buy a code reader from Kragen or another parts store like them, u need a "OBD 2" code reader

My cluster all lights come on and gages fluctuate while driving


so what works and what not.
so far we have cluster issues
does car drive, ok day and night.
and all accessories?
did engine stall driving?
did Head lights dim? on, driving?
my guess is the engine stalled or idled below 300rpm
and the ECU went to Key on self test mode, (they all do that)
watch the RPM guage? see that needle, ?
if it goes below 300 rpm that is engine stall.
or worse
This cars cluster is really just a digital display
so if the PCM cant talk to the cluster, the cluster will go nuts.
for freeze.
We use a scan tool to see whats up.
or use the cluster self test covered in the shop manual.
the cluster has 2 fuses that can be cracked/loss or corroded.
the cars battery can go weak.
if the charge/battery light glows, engine RPM good
then the alternator systems is failing
if the volt meter (if opted) in cluster drops below 14v, and engine is still running, the same, alternator system failure
or even a loose belt at the alternator.
if the battery voltage drops too low , all electrics go nuts.
and engine stalls.
what dies first with low battery , is luck of the draw....
so what was battery voltage
and engine RPM at the point of failure.??????????

Car stalled as I turned into my road. Turned key and it started right up. Has happened to me twice. No check engine light, no codes after hooking up to machine. Worried its gonna happen on major road. Any...


crank sensor fail this can happen some times with no codes. if the crank sensor dont get a reading the engine cuts out but when you turn the key after the stall it will read ok again and start.

Dash lights on my 2010 venza won't go off when driving on dash


are there some that do go off, ????
the ENGINE light glows when there are engines problems
you scan the PCM and it reports errors, YOU HAVE ERRORs, scan it.
the brakes come on, if engine stalls. or RPM on engine falls real low
about 300 RPM the engine can stall, (engine problems) and when it does that the dash goes to self test of dash lamps.
turn key, no start, see all those lamps doing there self test? bingo that.
if engine RPM are normal and the brake lamp comes on,, all this is in the lost operators guide int he glove box.
Brakes failure or hand brake is left on, it says that clearly and is true.

BMW car accelerating failures


The fault reason appears in the instrument panel or internal damage EML control module. EML system has self diagnosis function, also has the failure protection function, when the EML system failure, it can transmit the signal to the engine control module, common control solar term door position motor, maintain solar term door opening to suppress the rotation speed of the engine, so the fault that caused the engine speed can't go up. Use obd2 for automotive diagnostics , you can improve vehicle safety performance and driving more safer.

97 sunfire,2-door with sunroof. The airbag stays on. How can I reset it?


The airbag system with perform a self diagnostic when engine operation is ititiated. The airbag light will come on during the self check. If the diagnostic program find no faults the light will de-illuminate. But in this situation the light remain on which means the diagnostic program has detected a fault. There is no way to re set a failure on a self diagnostic. Repair of the system is the only option in this case.

Check engine light comes on after approx. one minute. My code reader gives me a 214 in continuous memory ( cylinder ID circuit failure). I clear the code and it comes back. What is giving me this code?...


look 214 is not a valid code for a 1995 escort, this is an OBD1 system. here is a list of trouble codes for this year of ford no matter the model.

You should find the diagnostic connector under your hood normally by the fender on the battery side. By just using your test light and a jumper wire, it will tell you what kind of problem you got.

KEY ON ENGINE OFF (KOEO) TEST
Model years 1984-1995 all models of Ford
1. Make sure engine is fully warmed. If in doubt, run engine at 2000 rpm for 2 minutes.
2. Turn ignition off and wait 10 seconds for system to shut off. Make sure A/C is off and transmission is in Park (automatic) or Neutral (manual).
3. Hook up light and jumper (or a tester if you have one). Turn key to ON (do not start engine). Read the codes.

How to do it?

Example code 23: your test light should flash 2 long consecutive flashes followed by 3 short pulses.

possably a vacuum leak. the check engine light comes on with an emmissions issue, ie vac leak, and it will not allow the cruise to work. once the error is fixed, your cruise should work properly again
