Test F

PINPOINT TEST F: THE LUGGAGE COMPARTMENT LAMP IS INOPERATIVE


Test F1:






Test F2-F4:






Test F5-F7:






Test F7-F10:






Normal Operation
The luggage compartment lamp is controlled through the REM. SSP relay 4 supplies power to the lamp through circuit 29S-LB4 (OG/BK). The luggage compartment lid ajar switch provides a ground signal to the REM through circuit 8-GL20 (WH/BK) which, in turn, provides a ground signal to the luggage compartment lamp through circuit 31S-LB25 (BK/BU).

Possible Causes
- luggage compartment lid ajar switch
- battery junction box (BJB) fuse 4 (10A)
- BJB
- REM
- circuit 29S-LB25 (OG/BU) open
- circuit 31S-LB25 (BK/BU) open
- circuit 31S-LB25 (BK/BU) short to ground
- 8-GL20 (WH/BK) short to ground
