Normal Operation
When any keypad button is pressed the smart junction box (SJB) sends power to the keyless entry keypad lamps on circuit 66 (LB) to assist the driver in entering his access code at night. The keyless entry keypad is grounded on circuit 1205 (BK).

Possible Causes
- Circuit 66 (LB) open or short to ground
- Circuit 1205 (BK) open
- Keyless entry keypad
