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 Keypad Switch Circuit Failure - is a continuous or on-demand DTC that sets when the SJB detects a short to ground on any of the keyless entry keypad input circuits CPK29 (GY/BU), CPK30 (VT/GN), or CPK31 (YE/GN). The DTC is also set if any of the keyless entry keypad buttons are actuated for longer than 2 minutes.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals and connectors
- Keyless entry keypad
- SJB
