run the fault codes first to determine what fault is occurring

I suggest you carefully read your owner's manual to discover the exact function of the wrench light.

I recently had experience of a GM model which had two lights on the dash. One light was a management light which would illuminate if a problem occurred that would affect emissions and the other light was a wrench light that would illuminate for other management faults that wouldn't affect emissions, such as turbo overboost.
The first light indicates a fault code has been recorded and diagnostic equipment would be needed to retrieve the code and extinguish the light but the second light resets with the turning off and on of the ignition. In both cases when the light is switched on it means the engine management has switched to an emergency get-you-home programme which usually results in a reduced power output - sometimes drastically reduced.

Whether this describes the system used on your car or not I cannot comment about but it does sound as though you need to make friends with someone who has some know-how and electronic diagnostic equipment.

Wrench means, workshop needed. If it does not come back, no problem. If it keeps coming back, visit a repair shop.

Sounds like 2 separate problems. The wrench light signifies that the truck goes into" limp home" mode and that there is a problem with your electronic speed control. As far as the truck pulling; is it doing it just driving without using the brakes? It could mean that you may need an alignment, tire rotation , low tire pressures or all of the above. Good luck to you

The oil light with wrench symbol means that your car needs an oil change and quickly. However, if you believe that's an error, use the Digital Instrument Cluster located on the dash to reset it or carry out the following steps to reset it:
1. Put the key into the ignition and switch to ON position
2. Once the dash lights have turn off - fully press the accelerator and release it three times in a row within five seconds
3. Now start the car and the error should have gone away

This symbol is a check engine Light which comes on when error codes are saved about problem with engine or electrics Get an error code reader and see the problem yourself rather than pay a garage to do it .

the 'wrench' symbol is a service light or possibly an engine managment symbol. if the car 'kinda' drive of a fashion then its computer has dropped onto 'limp home' mode and ur car needs to be put onto a diagnostic fault finder at a garage.
