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

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

Normal Operation
When the smart junction box (SJB) detects that a keyless entry 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 GD179 (BK/VT).

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