this comes right from the service manual: The SERVICE (wrench) telltale is turned on by the cluster when it receives a command from the Powertrain Control Module (PCM), Body Control Module (BCM), or the Electronic Brake Traction Control Module (EBTCM), the PCM or BCM will turn the SERVICE (Wrench) telltale on for all Non-emission related diagnostic trouble codes (DTCs) that require that a telltale be turned on.
The SERVICE (Wrench) telltale will also be turned on if the EBTCM has detected a fault in its own warning indicator system. if the Antilock Braking System (ABS) system cannot turn its own telltale, a message will be sent to the cluster to turn on the SERVICE (Wrench) telltale
The SERVICE(Wrench) telltale will be displayed for 2-3 seconds during startup for bulb check purposes.
you should have your engine checked out to make sure everything is working well
unhook the battery for 5 minutes thiss will erase all error codes (and preset radio stations) if the SES (service engine soon) light comes back on take it to a mechanic or buy a OBD2 code reader
Another way to disable the service engine soon light is to disconnect the battery for about 10-20 minutes.The most common reason for the service engine soon light to come on is that the gas cap wasn't tightened all the way.
How does one reset service engine light on 2000 Nissan Quest Thanks Bill
can you tell me why my 1999-2000 Chevy trailblazer light is on
Have vehicle scanned to determine the problem
The light shows that a service is due It is distance or time related.
you need to have the car's computer scanned to see what codes are making the service engine soon light appear.
That requires an OBDII engine scanner.
No it will not.
