NOTE

If wire 2740 cannot be identified at door switch, measure continuity across switch from

Turn battery disconnect switch to

OFF position (WP 0007).

Remove passenger side body stowage compartment door

switch (WP 0385), do not disconnect wires. Check for continuity between door switch

terminal wire 1479 (black) and a known good ground when switch is closed (door switch

is not pressed).

If there is continuity, go to Step 24.

Step 22.

Check for continuity across door switch between terminal wire 1479 (black) and

terminal wire 2740 (black).

If there is no continuity, replace door switch (WP 0385).
