DTC Set Conditions
WARNING: This page is about a different car, the 2004 Mitsubishi Eclipse. However, it is still accessible from the selected car via links, so may be relevant.
If the stoplight switch is on for five minutes or more while driving above 50 km/h (31 mph), or all of the stoplight bulbs are blown, it is judged there is a short circuit or open circuit in the stoplight switch. This causes DTC 26 to be set.
