well when gm designed there line of automobiles they were drinking, therefore not thinking very clear "dont drink and design"
use a code scanner!
With an OBD2 scanner.
The ASR dash light is a brake assist system/acceleration slip regulation light. When this light comes on in the Isuzu NPR truck, the on board computer in the vehicle detected a malfunction in the acceleration slip regulation and the vehicle needs to be taken for service.
You connect your floor shifter to your transfer case in a 4x4 Chevy truck 1993 by getting under the truck and looking for the rod that comes from the shifter to the transfer case. Then, use the pin connector to connect the rod.
When the service engine soon light comes on it means the computer has found a problem, it should post a code in the computer memory. Plug a scanner into the port and it should give you the code. From that you can look up what the code means and that will give you some idea of what the problem may be.
the hold light on on my mazda truck b 2600 stays on or flashing and it shut the engine off
yes
Need to know what the question is.
the diodes in the alternator have gone
the service engine light is on due to the fact that there is a problem with your truck, this is confirmed by the way your truck is running. you need to get a engine diagnostic check at an auto shop. may just need a tune-up, or the truck has a bad sensor, or engine woes.
If you have another light that says Check Engine, then the Service Engine Soon light means to change the oil/filter or perform some other maintenance item as listed in your owner's manual. You will see the other light when you turn on the ignition. If however there is no Check Engine light, this light means there is a problem with the emissions system.
it could be your transfer case, my need to be rebuilt.
