Chain protection
Two 60A fuse links in the battery electrical junction box protect the power circuits for the left and right lighting circuits in the CJB respectively. Field-effect transistors are used to protect all electrical circuits of external lighting devices (FET), located in the CJB, which detect overloads and short circuits.
Unipolar transistors react to the heat generated by the short circuit current. In a circuit with conventional protection, a short circuit would blow the fuse. The unipolar transistor, reacting to increased heat dissipation, turns off the circuit where it occurs. After the fault has been corrected, or after the transistor has cooled down, the circuit can function normally again. If the malfunction makes itself felt constantly, then the unipolar transistor will operate cyclically, turning the power on and off in this circuit. The CJB generates trouble codes that can be retrieved using the Land Rover approved diagnostic system. The fault code indicates the location of its occurrence, which helps in diagnosing.
Alarm
Outdoor lighting fixtures are used to turn the burglar alarm on and off. When the driver locks or unlocks the vehicle, the hazard warning lights flash several times to provide the driver with a visual signal that the lock or unlock was successful. For more information, see the chapter: Anti-theft system - active (419-01A Anti-theft system - active, Description and principle of operation).
Beep warning of lights on
If the ignition is off (power mode 0) or in the power supply position of the auxiliary equipment (power mode 4), and the rotary light switch is left in the parking light or headlight position, a warning chime will sound when the driver opens the door. The gong reminds the driver that the exterior lights have been left on. The source of the warning horn is a speaker located in the instrument panel that is activated when the CJB's high-speed CAN bus signals the door open and the ignition off.
Activating the Collision Warning
When from the Restraint Control Module (RCM) a collision is signaled, the CJB activates the hazard warning lights and turn signal warning lights located in the instrument panel. The hazard warning lights stay on until the ignition mode is switched to power mode 4 or power off mode 0 and the RCM stops transmitting the collision signal. For more information, see chapter: Airbag and Pretensioner Restraint System (SRS) (501-20B Secondary Restraint System Description and Operation).
Headlight timer
The CJB acts as a headlight timer that can remain on for some time after the driver exits the vehicle. This function is provided for the convenience of the driver, for whom the headlights illuminate the path.
This function can only be activated by turning on the headlight alarm using the left multifunction switch on the steering column. It can be disabled either by timeout or by re-activating the multi-function switch.
The default setting can be changed by Land Rover or an authorized dealer. The default time setting is set to 30s but can be changed to 0s (off), 30 s (default value), 60s, 90s, 120s, 150s and 180s. For more information, see the chapter: Information and Message Center (413-08 Information and Message Centre, Description and Operation).
