Lighting System: Overview Nissan Quest III

General precautions for service operations

1. Never work with wet hands.
2. Turn the lighting switch OFF before disconnecting and connecting the connector.
3. When checking the headlamp on/off operation, check it on vehicle and with the power connected to the vehicle-side connector.
4. Do not touch the headlamp bulb glass surface with bare hands or allow oil or grease to get on it. Do not touch the headlamp bulb just after the headlamp is turned off, because it is very hot.
5. When the bulb has burned out, wrap it in a thick vinyl bag and discard. Do not break the bulb.
6. Leaving the bulb removed from the headlamp housing for a long period of time can deteriorate the performance of the lens and reflector (dirt, clouding). Always prepare a new bulb and have it on hand when replacing the bulb.
7. Do not use organic solvent (paint thinner or gasoline) to clean lamps and to remove old sealant.

System Description

Control of the headlamp system operation is dependent upon the position of the combination switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives input requesting the headlamps (and tail lamps) illuminate. This input is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the headlamp high and headlamp low relay coils. When energized, these relays direct power to the respective headlamps, which then illuminate.

Low Beam Operation

With the lighting switch in 2ND position, the BCM receives input requesting the headlamps to illuminate. This input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the IPDM E/R controls the headlamp low relay coil. When energized, this relay directs power

1. through 15A fuse (No. 36, located in the IPDM E/R)
2. through IPDM E/R terminal 20
3. to front combination lamp RH terminal 1, and
4. through 15A fuse (No. 45, located in the IPDM E/R)
5. through IPDM E/R terminal 30
6. to front combination lamp LH terminal 1.

Ground is supplied

1. to front combination lamp LH and RH terminal 2
2. through grounds E9, E15 and E24.

With power and ground supplied, low beam headlamps illuminate.

High Beam Operation/Flash-to-Pass Operation

With the lighting switch in 2ND position and placed in HIGH or PASS position, the BCM receives input requesting the headlamp high beams to illuminate. This input is communicated to the IPDM E/R and combination meter across the CAN communication lines. The CPU of the combination meter controls the ON/OFF status of the HIGH BEAM indicator. The CPU of the IPDM E/R controls the headlamp high relay coil. When energized, this relay directs power

1. through 10A fuse (No. 40, located in the IPDM E/R)
2. through IPDM E/R terminal 27
3. to front combination lamp RH terminal 3, and
4. through 10A fuse (No. 38, located in the IPDM E/R)
5. through IPDM E/R terminal 28
6. to front combination lamp LH terminal 3.

Ground is supplied

1. to front combination lamp LH and RH terminal 4
2. through grounds E9, E15 and E24.

With power and ground supplied, the high beam headlamps illuminate.

The headlamp system for Canada vehicles is equipped with a daytime light control unit that activates the high beam headlamps at approximately half illumination whenever the engine is running. If the parking brake is applied before the engine is started the daytime lights will not be illuminated. The daytime lights will illuminate once the parking brake is released. Thereafter, the daytime lights will continue to operate when the parking brake is applied.

Control of the fog lamps is dependent upon the position of the combination switch (lighting switch). The lighting switch must be in the 2ND position or AUTO position (LOW beam is ON) for front fog lamp operation.

When the lighting switch is placed in the fog lamp position, the BCM (body control module) receives input signal requesting the fog lamps to illuminate. When the headlamps are illuminated, this input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the front fog lamp relay coil. When activated, this relay directs power to the front fog lamps.
