  27. Checking Keypad Input  - Disconnect control module connector J2. Check for short-to-ground between keypad and connector J2. A reading of 100,000 ohms or less indicates a short. If a short is present, go to next step. If short is not present, go to step 29).
  28. Remove door trim panel. Disconnect keypad connector. Check for short between keypad connector and ground. Resistance less than 100,000 ohms indicates a short.
