When the headlamp switch is placed in the PARK or ON position, the dash integration module (DIM) Park Lamp Switch input is grounded via CKT 301 (BRN/WHT).

The dash integration module (DIM) supplies battery positive voltage (B+) to the PRK LP relay coil when the headlamps or park lamps need to be on or when the ignition switch is in the ON position. Battery positive voltage (B+) is supplied at all times to the PRK LP relay switch. When the park lamps are to be active, the DIM grounds the PRK LP relay coil. The coil is energized, closing the switch contacts. Battery positive voltage (B+) is supplied to the rear fuse block LP PK R Fuse, LP PK L Fuse, and DIMR Fuse. The LP PK R Fuse supplies battery positive voltage (B+) to the RH park lamps. The LP PK L Fuse supplies battery positive voltage (B+) to the LH park lamps. The LH and RH park lamps are permanently grounded, so all park lamps have power and ground, and then light. The DIMR Fuse supplies battery positive voltage (B+) to the DIM Park Lamp input for interior lamps dimming, the license lamps, the underhood lamp, and the cornering lamps. The license lamps are permanently grounded, so both license lamps have power and ground, and then light.

The LIGHTS ON indicator may be ON during any power mode except for START. The IPC illuminates the LIGHTS ON indicator under the following conditions:

Perimeter lighting will activate the vehicle's park lamps, backup lamps, and high beam headlamps for 20 seconds or until a door is opened after a driver's door unlock command using the keyless entry transmitter.

Battery positive voltage (B+) is supplied at all times to the turn signal/hazard flasher module in the hazard switch assembly from the rear fuse block TSIG/HAZ Fuse. The turn signal/hazard flasher module is permanently grounded. Battery positive voltage (B+) is supplied with the ignition switch in the ON or START position to the turn signal switch in the steering column from the rear fuse block IGN 1 Fuse.

When the turn signal switch is placed in the position to indicate a LH turn, battery positive voltage (B+) is input to the turn signal/hazard flasher module Left Turn Input. In response to this input, the turn signal/hazard flasher module supplies battery positive voltage (B+) in an on and off flashing pattern to the LH turn lamps. The LH turn lamps are permanently grounded so the LH turn lamps light when they have power and ground and turn off while power is removed.

When the turn signal switch is placed in the position to indicate a RH turn, battery positive voltage (B+) is input to the turn signal/hazard flasher module Right Turn Input. In response to this input, the turn signal/hazard flasher module supplies battery positive voltage (B+) in an on and off flashing pattern to the RH turn lamps. The RH turn lamps are permanently grounded so the RH turn lamps light when they have power and ground and turn off while power is removed.

The left turn indicator may only be ON during RUN. The IPC illuminates the left turn indicator when the IPC detects a high (voltage) input condition from the left turn signal. The signal source comes from the exterior lighting system via a discrete input. The indicator turns OFF within 150 milliseconds after the cluster detects the high input is low.

If the IPC determines that the turn signal remains ON for more than 1.6 km (1 mile), the IPC also sends a class 2 serial data message requesting the chime to sound and displays the TURN SIGNAL ON message on the DIC.

The right turn indicator may only be ON during RUN. The IPC illuminates the right turn indicator when the IPC detects a high (voltage) input condition from the right turn signal. The signal source comes from the exterior lighting system via a discrete input. The indicator turns OFF within 150 milliseconds after the cluster detects the high input is low.

If the IPC determines that the turn signal remains ON for more than 1.6 km (1 mile), the IPC also sends a class 2 serial data message requesting the chime to sound and displays the TURN SIGNAL ON message on the DIC.

When the hazard switch is pressed, the switch contacts close and the turn signal/hazard flasher module Hazard Input is grounded. In response to this input, the turn signal/hazard flasher module supplies battery positive voltage (B+) in an on and off flashing pattern to all turn lamps. All turn lamps and both turn indicators then light as described above.

When a THEFT is occurring, the dash integration module (DIM) will ground the turn signal/hazard flasher module Hazard Input.

Battery positive voltage (B+) is supplied at all times to the stoplamp/BTSI switch from the rear fuse block STOP LP Fuse. When the brake pedal is pressed, the stoplamp/BTSI switch contacts close and battery positive voltage (B+) is supplied to the center high mounted stop lamp (CHMSL) and the tail/stop lamps. The center high mounted stop lamp (CHMSL) and tail/stop lamps are permanently grounded . The stop lamps light when they receive both power and ground.

When the park lamps are on, battery positive voltage (B+) is supplied to the turn signal switch. When the turn signal switch is placed in the position to indicate a LH turn, battery positive voltage (B+) is supplied to the LH cornering lamp. When the turn signal switch is placed in the position to indicate a RH turn, battery positive voltage (B+) is supplied to the RH cornering lamp. Both cornering lamps are permanently grounded. The cornering lamps light when they receive both power and ground.

When the park lamps are on, battery positive voltage (B+) is supplied to the underhood lamp. The underhood lamp is permanently grounded. When the hood is opened, the switch in the underhood lamp closes and supplies ground to the bulb in the underhood lamp. The underhood lamp lights when it receives both power and ground.

Battery positive voltage (B+) is supplied at all times to the STANDING LP relay coil and switch in the rear compartment relay center from the rear fuse block EXPORT LGT Fuse. Battery positive voltage (B+) is supplied through the normally closed relay contacts of the STANDING LP relay to the POSN LP R relay coil and the POSN LP L relay coil in the rear compartment relay center. When the gear selector is in the PARK position, the dash integration module (DIM) grounds the STANDING LP relay coil removing battery positive voltage (B+) from the POSN LP R relay and POSN LP L relay. The position lamps light only with the ignition switch in the OFF position.

Battery positive voltage (B+) is supplied at all times to the POSN LP R relay normally open switch from the rear fuse block EXPORT LGT Fuse. When the headlamp switch is placed in the RH PARK position, the POSN LP R relay coil is grounded through the headlamp switch RH PARK switch contact. The coil is energized, closing the switch contacts from the normally open position. Battery positive voltage (B+) then is supplied to the RH position lamp and the RH tail/stop lamp. The position lamp and tail/stop lamp are permanently grounded so the RH position lamp has power and ground, and then lights. When the POSN LP R relay is in its normally closed position, battery positive voltage (B+) is supplied through the relay to the RH position lamp and the RH tail/stop lamp.

Battery positive voltage (B+) is supplied at all times to the POSN LP L relay normally open switch from the rear fuse block EXPORT LGT Fuse. When the headlamp switch is placed in the LH PARK position, the POSN LP L relay coil is grounded through the headlamp switch LH PARK switch contact. The coil is energized, closing the switch contacts from the normally open position. Battery positive voltage (B+) then is supplied to the LH position lamp and the LH tail/stop lamp. The position lamp and tail/stop lamp are permanently grounded so the LH position lamp has power and ground, and then lights. When the POSN LP L relay switch is in its normally closed position, battery positive voltage (B+) is supplied through the relay to the LH position lamp and the LH tail/stop lamp.
