Central Junction Box: Notes

The Central Junction Box (CJB) is an integrated unit located behind the instrument panel on the passenger side of the bulkhead. The CJB contains fuses, relays and a number of microprocessors which control the power supply and functionality of the interior lighting system and other vehicle systems.

The interior lamps are controlled by the CJB and have two types, Courtesy (switched by the doors; key; etc) and Demand lighting (controlled by the user). The Courtesy mode divided into Manual (the interior lamps can be switched on and off using the momentary and latching switches adjacent to each lamp or disabled completely using the same switches) and Automatic (the interior lamp functionality is controlled by the CJB on receipt of various input signals).
