Circuit/System Verification
- Wiper switch in the LO position, verify the scan tool Windshield Wiper Switch parameter is Low.
- Wiper switch in the HIGH position, verify the scan tool Wiper High Speed Switch parameter is Active
- Wiper switch in the INT position, verify the scan tool Windshield Wiper Switch parameter is Intermittent.
- Wiper switch in the INT position, observe the scan tool Wiper Delay Setting parameter while cycling the delay adjustment switch from long delay to short delay. The parameter should cycle between D1 and D5 as each delay position is selected.
