Check Output
WARNING: This page is about a different car, the 2019 Subaru Ascent. However, it is still accessible from the selected car via links, so may be relevant.
- Check the voltage between connector terminals.
Preparation tool:
Circuit tester
Terminal No. Inspection conditions Standard 2 - 3 Apply battery voltage between terminals 1 (+) - 3 (-). When pressing-in the end of the stop light switch to make the length (a) 3.6 mm (0.14 in) (the actual length will be a little shorter than 3.6 mm (0.14 in)), output voltage turns OFF. 0.5 V or less Apply battery voltage between terminals 1 (+) - 3 (-). When returning the end of the stop light switch to make the length (a) 3.6 mm (0.14 in) (the actual length will be a little longer than 3.6 mm (0.14 in)), output voltage turns ON. 12 V 4 - 3 Apply battery voltage between terminals 5 (+) - 3 (-). When pressing-in the end of the stop light switch to make the length (a) 4.5 mm (0.18 in) (the actual length will be a little shorter than 4.5 mm (0.18 in)), output voltage turns ON. 12 V Apply battery voltage between terminals 5 (+) - 3 (-). When returning the end of the stop light switch to make the length (a) 4.5 mm (0.18 in) (the actual length will be a little longer than 4.5 mm (0.18 in)), output voltage turns OFF. 0.5 V or less - Replace the stop light switch assembly if the inspection result is not within the standard value.
