Lighting System: Overview Nissan Versa I

System Description

Headlamp operation is controlled by the BCM (body control module) based on inputs from the combination switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM receives an input signal requesting the headlamps (and tail lamps) illuminate. The BCM sends a signal, via the CAN communication lines, to the IPDM E/R (intelligent power distribution module engine room) requesting the headlamps be turned ON. The CPU (central processing unit) located in the IPDM E/R controls ground for the headlamp high and headlamp low relay coils. These relays direct power to the respective headlamps, which then illuminate.

Low Beam Operation

With the lighting switch in 2ND position, the BCM receives an input signal requesting the headlamps to illuminate. The BCM then sends a signal, via the CAN communication lines, to the IPDM E/R requesting the low beam headlamps be turned ON. The CPU located in the IPDM E/R controls ground to the headlamp low relay coil, which when energized, directs power

1. through 15A fuse (No. 41, located in IPDM E/R)
2. through IPDM E/R terminal 54
3. to headlamp RH terminal 3, and
4. through 15A fuse (No. 40, located in IPDM E/R)
5. through IPDM E/R terminal 52
6. to headlamp LH terminal 3.

Ground is supplied

1. to headlamp RH and LH terminals 2
2. through grounds 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 high beam switch in the HIGH position, the BCM receives an input signal requesting the headlamp high beams to illuminate. The flash to pass feature can be used any time and also sends a signal to the BCM. This input signal is then communicated to the IPDM E/R and the combination meter via the CAN communication. The CPU located in the IPDM E/R controls the headlamp high relays (LH and RH), which when energized, directs power

1. through 10A fuse (No. 34, located in IPDM E/R)
2. through IPDM E/R terminal 56
3. to headlamp RH terminal 1, and
4. through 10A fuse (No. 35, located in IPDM E/R)
5. through IPDM E/R terminal 55
6. to headlamp LH terminal 1.

Ground is supplied

1. to headlamp RH and LH terminal 2
2. through grounds E15 and E24.

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

The BCM sends a signal, via the CAN communication lines, to the combination meter requesting the high beam indicator lamp be turned ON.

CAN COMMUNICATION SYSTEM DESCRIPTION

Refer to " SYSTEM DESCRIPTION ".

Scheme 1

Headlamp operation is controlled by the BCM (body control module) based on inputs from the combination switch (lighting switch). When the lighting switch is placed in the 2ND position, the BCM receives an input signal requesting the headlamps (and tail lamps) illuminate. The request is then communicated to the IPDM E/R (intelligent power distribution module engine room) via the CAN communication lines. The CPU (central processing unit) located in the IPDM E/R controls ground for the headlamp high and headlamp low relay coils. These relays direct power to the respective headlamps, which then illuminate. When the headlamp switch is OFF or in the 1ST position (parking lamps ON), the parking brake is released and the engine is running, the IPDM E/R de-energizes the headlamp relays and supplies ground to the daytime light relay 1 to actuate the daytime light function.

With the lighting switch in 2ND position, the BCM receives an input signal requesting the headlamps to illuminate. This input signal is communicated to the IPDM E/R via the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp low relay coil, which when energized, directs power

1. through 15A fuse (No. 41, located in IPDM E/R)
2. through IPDM E/R terminal 54
3. to daytime light relay 2 terminals 1 and 5 (energizing the relay)
4. through daytime light relay 2 terminal 3
5. to front combination lamp RH terminal 3, and
6. through 15A fuse (No. 40, located in IPDM E/R)
7. through IPDM E/R terminal 52
8. to front combination lamp LH terminal 3.

Ground is supplied

1. to front combination lamp LH terminal 2
2. through grounds E15 and E24
3. to headlamp RH terminal 2 via
4. daytime light relay 1 terminals 3 and 4
5. through grounds E15 and E24.

With power and ground supplied, low beam headlamps illuminate.

High Beam/Flash-to-Pass Operation

With the lighting switch in 2ND position and high beam switch in the HIGH position, the BCM receives input signal requesting the headlamp high beams to illuminate. The flash-to-pass feature can be used any time and also sends a signal to the BCM. This input signal is communicated to the IPDM E/R and the combination meter via the CAN communication lines. The CPU located in the IPDM E/R controls the headlamp high relay coil, which when energized, directs power

1. through 10A fuse (No. 34, located in IPDM E/R)
2. through IPDM E/R terminal 56
3. to front combination lamp RH terminal 1, and
4. through 10A fuse (No. 35, located in IPDM E/R)
5. through IPDM E/R terminal 55
6. to front combination lamp LH terminal 1.

Ground is supplied

1. to front combination lamp LH terminal 2
2. through grounds E15 and E24, and
3. to front combination lamp RH terminal 2 via
4. daytime light relay 1 terminals 3 and 4
5. through grounds E15 and E24.

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

The BCM sends a signal to the combination meter requesting the high beam indicator lamp to turn ON.

Daytime Light System Operation

With the lighting switch in the OFF or 1ST position (parking lamps ON), the BCM receives inputs requesting the headlights off. If the parking brake is released and the engine is running, the BCM then sends a signal, via the CAN communication lines, requesting the IPDM E/R to activate the daytime light system. The CPU located in the IPDM E/R controls the daytime light relay 1 coil, which when energized, directs power

1. from daytime light relay 1 terminal 3
2. to front combination lamp RH terminal 2
3. through front combination lamp RH high beam terminal 1
4. to IPDM E/R terminal 56
5. through 10A fuse (No. 34, located in IPDM E/R) and
6. through both de-energized headlamp high relays
7. to 10A fuse (No. 35, located in IPDM E/R)
8. through IPDM E/R terminal 55
9. to front combination lamp LH terminal high beam 1.

Ground is supplied

Scheme 2

The front fog lamps are controlled by lighting switch inputs to the BCM (body control module).

The BCM requests the front fog lamps over the CAN communication lines to the IPDM E/R. The CPU (central processing unit) of the IPDM E/R controls the front fog lamp relay coil ground. When energized, the relay directs power to the front fog lamps.
