What's that warning light? RRC Exclamation mark

[burn_e]

We have here a 1990 RRC 3.9i GCC spec (low tech, no code display)
Have no Owners manual to read what this means.

We are talking here about the light with the exclamation mark and yellow/amber colour.



Had the same light before and disconnecting the battery solved the issue for a while, but now its back...

The light came up again a few times and I just reset all by diconnecting the negative on the battery.

BTW this model is not equipped with traction control or cats (therefore no o2 sensors)!

today something new came up - the light got on while driving.
what would be your next guess to check?


So guys put the thinking caps on and help me with this!

For a start:
Which sensors are checked from the ECU at the start process?
Which sensors play a role after a while driving?

Why I am asking - after reseting the car the light comes up while driving and moderate throttle. Tried also reving the engine stationary and it didnt came up.

Thats where the "Check Engine" light is on a NAS RRC. So its probably that.

Is there a code readout box under the passenger seat? If not, you have a simple system that could only mean check these things: Airflow meter, O2's (which you dont have to worry about), TPS, ignition misfire.

ohhh, just good that its stoppable by disconnecting the battery.

So now back to business, please!

I'll check the owner's manual on my 1992.

My owner's manual says the same thing as Sven said above. Instead of an exclamation mark the U.S. ones seem to have the words "Check Engine" in the same location. This corresponds to the codes stored in the underseat computer display. Must have put a symbol instead of words for use in a wide range of international markets.

Only NAS trucks have an underseat display...

This UK forum suggested that the exclamation mark is used as a generic symbol meaning some kind of engine fault has developed and to stop the vehicle as soon as possible and check everything out. Here is the link:
