FRONT FOG LAMP OPERATION

When the lighting switch is in front fog lamp ON position and also in 1ST or 2ND position or AUTO position

(headlamp is ON), the BCM detects FR FOG ON and the HEAD LAMP1, 2 ON or the AUTO LIGHT ON. The

BCM sends a front fog lamp request ON signal through the CAN communication lines to the IPDM E/R. The

IPDM E/R then turns ON the front fog lamp relay sending power to the front fog lamps.

The combination meter also receives a front fog lamp request ON signal through the CAN communication

lines at which time it turns the front fog indicator ON.

TURN SIGNAL OPERATION

When the turn signal switch is in LH or RH position with the ignition switch in ON position, the BCM detects the

TURN RH or TURN LH ON request. The BCM outputs the flasher output signal to the respective turn signal

lamp. The BCM sends a turn indicator signal ON request through the CAN communication lines to the combi-

nation meter. The combination meter then activates the appropriate turn signal indicator and audible buzzer.

HAZARD LAMP OPERATION

When the hazard switch is in ON position, the BCM detects the hazard switch signal ON. The BCM outputs the

flasher output signal (right and left). The BCM sends a hazard indicator signal ON request through the CAN

communication lines to the combination meter. The combination meter then activates the hazard indicator and

audible buzzer.

REMOTE KEYLESS ENTRY OPERATION

The remote keyless entry receiver transmits Intelligent Key signal to BCM, then BCM controls hazard lamps.
