- Disconnect the Steering Column harness to I/P harness inline connector C201.
- Connect a DMM from the accessory voltage supply circuit terminal to the windshield wiper switch signal 2 circuit terminal in the steering column connector half.
- Operate the windshield wiper switch from Off to Mist, Delay 1 through 5, Low, and High.
