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 GD134 (BK/VT).
- DTC B1624 (Lamp Keypad Output Open Circuit) - 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) - a continuous DTC that sets when the SJB detects a short to ground on the keyless entry keypad illumination circuit CPK28 (WH/GN).
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Keyless entry keypad
- SJB
