How to Reset the Computer on a 1992 GMC Jimmy

Starting in the late 1970s, vehicles were equipped with on-board computers that were specific to each vehicle. This often meant a trip to the dealership service center for diagnosis and computer resets. The 1992 GMC Jimmy was no exception. A GM-specific computer scan tool must be used to read and clear codes as well as reset the computer. In 1996, the second phase of on-board diagnostics standardized the equipment needed to perform this task so most all repair stations could do this for every type of later model vehicle.

Instructions

    1

    Open the hood of your 1992 GMC Jimmy.

    2

    Remove the black, negative battery terminal bolt from the batterys side post with an 8 mm box-end wrench turned counterclockwise.

    3

    Detach the red, positive battery terminal bolt from the batterys side post with the wrench.

    4

    Turn on the headlight switch inside the passenger cab to discharge any stored voltage in the capacitor. Wait five to 10 minutes.

    5

    Reconnect the red, positive battery terminal bolt to the batterys side post first and tighten it with the wrench.

    6

    Reattach the black, negative battery terminal bolt to the batterys side post and tighten it with the wrench.
