Stop Lamps Function
1.Necessary conditions to switch ON the stop lamps:
a. Pushing on the brake pedal.
2. Necessary conditions to switch OFF the stop lamps:
a. Releasing the brake pedal.
3. Functional diagram
Auto Light Function
1.The Auto light function is active when the Head lamp switch is positioned to 'Auto' and the Key is in RUN position.
The auto light sensor is powered on the status ACC, START and RUN of the key position. Based on the Auto light
sensor values corresponding to the exterior brightness level, it controls automatically the lighting of the Park and tail
lamps or / and the Head lamps Low Beam depending on the country.
2. Auto light Sensor detection table
Mode Tail Lamps
Head Lamps Low Beam
Lux (Lux) Voltage(V) Lux (Lux)Voltage(V)
ON < 24 ± 5.2 <1.77 ± 0.08V Same as Tail lamps
OFF > 48 ± 10.5 > 3.47 ± 0.1V Same as Tail lamps
Drl Function
1.The Auto DRL function operates the Head lamps High Beam at 50% of full illumination.
The park and tail are managed by the auto light sensor.
The Auto DRL function is active if:
a. The ignition switch is on RUN position
b. The engine is running.
c. The Park brake switch is OFF.
2. The DRL function is inactive when one of above conditions is released.
When the DRL function is active, the Head lamps High Beam can't be turned ON, except for the Flash To Pass
activation.

switch, the status of the ABS EBD warning, the status of the brake fluid sensor and the speed of the vehicle.
The IPM sends the park brake indicator control on the CAN network.
The indicator is lighted if the vacuum switch or ABS EBD warning are on or brake fluid sensor is low or park brake
switch is on.
If the speed of the vehicle is over 10 km/h and ignition switch is on the status RUN the park brake indicator control is
blinking at 50% duty in 0.6 second if Parking Brake switch Input is active. In this case Vacuum switch, ABS EBD
warning and Brake Fluid sensor are ignored.
The park brake indicator is blinking on the same time that the chime is ringing. If a CAN signal among Vacuum switch,
EBD warning or Brake Fluid Sens switch is INVALID, out of range or not received this CAN signal is considered to be
OFF.
If VehicleSpeed CAN signal is INVALID or not received, it is considered to be 0 kph.
Charging Voltage Control
The IPM receives on analog input the voltage of generator and sends a warning.
When the voltage of generator L pass strictly above 10V, the state of the CAN variable.
Turn Indicators Status
The status of the turn indicators are sent on the CAN network when the CAN network is available.
High Beam Status
The status of the high beam is sent on the CAN network when the CAN network is available.
Front Fog Lamp Status
The status of the front fog lamp (lightning and state of the bulbs) is sent on the CAN network when the CAN network
is available.
Doors Open Warning
The RAM receives on digital input the status of the driver door open switch and sends it on the CAN network.
The RAM receives on digital input the status of the passenger door open switch and sends it on the CAN network.
The RAM receives on digital input the status of the left sliding door open switch and sends it on the CAN network.
The RAM receives on digital input the status of the right sliding door open switch and sends it on the CAN network.
When vehicle speed is under 10 kph, with ignition key not inserted and any door OPEN, DoorsOpenWngCtrl stays ON
for 20 min and then is turned OFF.
Tailgate Open Switch Status
When vehicle speed is under 10 kph, ignition key is inserted and Tailgate open switch is OPEN, Tailgate Open
warning stays ON forever (IPM can enter sleep mode).
When vehicle speed is under 10 kph, with ignition key not inserted and lgate open switch is OPEN, Tailgate Open
warning stays ON for 20 min and then is turned OFF.
Chime Control
1.The chime warns the driver that a problem is occurred.
These warning are:
a. Seat belt
b. Parking on
c. Over speed
d. Key reminder
e. Light Warning
f. Doors Open
g. Tailgate open warning
2. Chime sound priority:
a. 1st : Seatbelt warning
b. 2nd : Overspeed warning
c. 3rd : Door open warning
d. 4th : T/Gate open warning
e. 5th : Key operated warning
f. 6th : Parking Brake warning
Page 1230 of 1575

g.7th : Light ON warning
h. 8th : Key learning sound
3. If two different warning condition happen at the same time, chime should work only for the highest warning
condition.
4. Cluster indicators should work for two warning behavior.
5. Behavior Description
Seat Belt Warning
The IPM receives on digital input the status of the seat belt switch.
The chime is activated during 6 second when the seat belt is not fastened.
The chime will stop immediately if the seat belt is fastened during the 6 seconds of the chime.
Park Brake Warning
The IPM receives on digital input the status of the parking brake switch.
The IPM receives the speed of the vehicle by the CAN network.
The chime is activated when the parking brake is on, ignition switch is on RUN and speed vehicle is over 10 km/h.
The park brake indicator is blinking at the same time that the chime is ringing.
Over Speed Warning
The IPM receives the overspeed warning by the CAN network.
The chime is actived when the overspeed speed warning is on the state Overspeed.
Key Reminder Warning
The IPM receives the status of the key on digital input.
The IPM receives the status of the driver door open switch by the CAN network.
The chime is activated when key is inserted and the driver door is open.
Light Warning
The IPM receives the status of the driver door open switch by the CAN network.
The light chime warning is activated when the driver door is open and the park and tail lamps are turned on.
Doors Open Warning
The RAM receives on digital input the status of the driver / passenger / left sliding / right sliding door open switch and
sends it on the CAn network.
The IPM receives by CAN network the speed of the vehicle.
The doors open warning chime is activated when one or several of the 4 doors is opened and the speed of vehicle is
over 10km/h.
Tailgate Open Warning
The RAM receives on digital input the status of the tailgate open switch and sends it on the CAN network.
The IPM receives by CAN network the speed of the vehicle.
The tailgate open warning chime is activated when the tailgate is opened and the speed of vehicle is over 10km/h.
