Normal Operation
The smart junction box (SJB) sends voltage signals to the keyless entry keypad through circuits CPK29 (GY/BU), CPK30 (VT/GN), and CPK31 (YE/GN). When a button is pressed on the keypad, one or more of the voltage signals is routed to ground through circuit GD133 (BK). Based on the input received, the SJB is able to determine which number on the keypad is pressed.

DTC B2A26 - is an on-demand DTC that sets when the SJB detects a short to ground from any of the keypad input circuits.

Possible Causes
- Circuit CPK29 (GY/BU) open or short to ground
- Circuit CPK30 (VT/GN) open or short to ground
- Circuit CPK31 (YE/GN) open or short to ground
- Circuit GD133 (BK) open
- Keyless entry keypad
- SJB
