Side repeater lamp
Item name | Spare part number | Description |
1 | - | Side indicator repeater |
2 | - | lamp holder |
3 | - | Spring retainer |
Side turn signal repeaters are built into the driver's and front passenger's doors under the rear-view mirrors. The lanterns are inserted into the hole in the door panels, where they are held by spring clips. To remove the lantern, you need to move it back, and then release the front edge of the lantern from the hole in the door. In the cartridges of the side turn signal repeaters, lamps without a base with a power of 5 W are installed.
Side turn signal repeaters have the same purpose as the front and rear turn indicators. They are activated by the left multifunction stalk, as well as the hazard warning switch. The multifunction steering column switch only works when the ignition switch is in position II (ignition on), the hazard switch operates in any circuit condition. Side turn signal repeaters operate with an on / off cycle of 0.38 seconds. If one of the lamps in the direction indicators fails, the remaining lamps will continue to operate at normal frequency.
Left multifunction stalk
Item name | Spare part number | Description |
1 | - | Right turn signal lamp |
2 | - | High beam signaling |
3 | - | Left turn signal lamp |
4 | - | Switching on high beam headlights |
The multifunction steering column switch is located on the left side of the steering column and performs the following functions:
- Switching headlights from low beam to high beam and vice versa
- High beam signaling
- Switching on the left / right turn signal
- Trip computer functions. For more information, please refer to the Information and Message Center (413-08)
Different circuits are also used to activate the direction indicators. When switching, the corresponding circuit is closed to «mass», recognized by the CJB, which includes the required direction indicators.
Alarm
The alarm is controlled by a non-latching switch located in the center of the control panel. The alarm can be turned on at any time, regardless of the position of the key in the ignition.
When the alarm is activated, all front, rear and side turn indicators are turned on, which operate in the mode described above. The indicators of the left and right direction indicators located on the instrument panel also flash. The direction indicators flash in the following mode: 380 ms - signal, 380 ms - pause. If the hazard warning mode is active, it overrides any previously set turn signal state.
If the vehicle is transporting a trailer, its direction indicators will also flash at the same frequency as the vehicle's direction indicators. The trailer indicator on the dashboard also flashes. If the trailer turn signal lamp burns out, the trailer indicator will not flash.
The hazard warning system can also be activated by a collision signal from the SRS controller. This signal is received by the CJB switching unit, which activates the alarm. The alarm can be disabled by turning the ignition key to position I or 0. It can also be disabled by a signal from the SRS controller. For more information refer to Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) (501-20B)
License plate lights
The two license plate lights are integrated into the tailgate handle and are located above the license plate in the upper door leaf. Each license plate light uses a 5W baseless lamp. The lights are fastened with latches in the handle of the upper sash of the rear door. They can be released with a small flat head screwdriver.
The license plate lights are always on when the sidelights or headlights are on.
Upper brake light
Item name | Spare part number | Description |
1 | - | Upper brake light |
2 | - | Frame |
The upper brake light is located at the top of the tailgate. The tailgate glass washer nozzle is also installed in the brake light housing.
The brake light has a plastic housing with a red diffuser. Stop signal illuminated by LEDs (LED).
The upper brake light is switched on simultaneously with the main one, when the ignition switch is in position II and the limit switch is closed when the brake pedal is pressed.
The upper brake light can be activated by the anti-lock system when the controlled descent function is active (HDC). The signal from the ABS closes the relay contacts, through which electricity is supplied to the brake light. For more information refer to Anti-Lock Control - Traction Control (206-09A)
Trailer exterior lights
Depending on the market, the vehicle may be equipped with different types of sockets for connecting the trailer's electrical wiring. See the Electrical Reference Library for details (ERL).
Central switching unit (CJB) constantly monitors the status of the direction indicator lamps and can determine if more than two lamps are installed (side turn signal repeaters are not controlled). If a trailer is detected (by number of lamps), the trailer indicator on the instrument panel will flash in the same rhythm as the vehicle's direction indicators.
If one or more of the direction indicators of the vehicle or trailer fails, the indicator will not flash, which for the driver is a sign of a burned out lamp.
Diagnostics
Diagnostic bus connector (diagnostic connector) located at the bottom of the control panel trim on the driver's side, under the steering column. Monitoring of various functions of the lighting system is carried out by different vehicle systems that store fault codes in memory. These codes can be read using a T4 scan tool or other similar scanner.
AFS Controller Fault Monitoring
The AFS controller monitors malfunctions in the AFS system and the dynamic headlight range control system. The controller stores diagnostic trouble codes (DTC) when you experience the symptoms listed in the following table.
Description of symptoms that cause DTCs to be logged | Symptom reported by customer | Possible reason |
Malfunction of the communication line with the gearmotor of the right or left adaptive headlight | Headlight course control system does not work | Open or short circuit to "mass" |
Malfunction of the gearmotor of the right or left adaptive headlight | Headlight course control system does not work | Open or short circuit to "mass" |
Malfunction of the electric motor of correction of an inclination of the right or left headlight | Headlight range adjustment not working | Open or short circuit to "mass" or on a 12 V circuit |
CAN bus failure | The headlight beam control and headlight range adjustment systems do not work. It is likely that other systems in the car are not working either | Open or short circuit to "mass" or on a 12 V circuit |
Central switching unit (CJB)
The CJB monitors the status of the lighting, relay, and switch circuits. When a fault is detected, the CJB records a fault code that can be read using the T4 scan tool or similar scanner.
