Code 25, Short To Battery In Steering Column: Description
WARNING: This page is about a different car, the 1991 Geo Storm, 1991 Geo Metro, 1990 Geo Storm, and 1990 Geo Metro. However, it is still accessible from the selected car via links, so may be relevant.
DERM grounds FORCE LOW input (terminal No. A10), and then monitors voltage at SENSE LOW input (terminal No. A6). If voltage is greater than 3 volts, Code 25 will set. Code 25 is an indication of a short to system voltage in steering column arming sensor or associated wiring. In addition, this code can set if actual resistance of 100-ohm resistor within resistor module is too high or open.
