Test H: The Keyless Entry Keypad Illumination Is Inoperative/Does Not Operate Correctly

PINPOINT TEST H: THE KEYLESS ENTRY KEYPAD ILLUMINATION IS INOPERATIVE/DOES NOT OPERATE CORRECTLY

Normal Operation
When the smart junction box (SJB) detects that a keyless entry keypad button is pressed, the SJB provides voltage for the keyless entry keypad illumination through circuit CPK28 (WH/GN). Ground for the keyless entry keypad illumination is provided through circuit GD133 (BK).

- DTC B1624 (Lamp Keypad Output Open Circuit) - is an on-demand DTC that sets when the SJB detects an open or short to voltage on the keyless entry keypad illumination output circuit CPK28 (WH/GN).
- DTC B1626 (Lamp Keypad Output Short Circuit to Ground) - is a continuous DTC that sets when the SJB detects a short to ground on the keyless entry keypad illumination output circuit CPK28 (WH/GN).

This pinpoint test is intended to diagnose the following:
- Wiring, terminals and connectors
- Keyless entry keypad
- SJB
