Exterior Lamp Emergency Flashing System—SEO 6J7

SEO 6J7 provides a high-beam headlamps flashing module, rear lamps

flashing and control wire for a customer-furnished switch to turn the

module on or off. The flasher control wire is coiled in the passenger’s

side footwell under the instrument panel. This control lead may be

combined with the interior wiring leads for SEO 6J3 when that option is

ordered with SEO 6J7.

The headlamps flashing module is located at the inboard end of the

passenger’s side headlamps assembly. The headlamps flashing module

is activated by the application of 12 volts to a dark green/red wire

coiled in the passenger’s side footwell. When activated, the driver’s and

passenger’s side high-beam headlamps and the high-beam instrument

panel cluster light will flash alternately at 2.4 flashes per second.

During daylight conditions, the Daytime Running Lamps (DRL) are

automatically turned off whenever the headlamps flasher module is

activated. During nighttime conditions, the low-beam headlamps turn

on automatically while the high-beam headlamps flash. Turning on the

high-beam headlamps manually with the turn signal/multifunction lever

will override the flashing module and the high-beam headlamps will

operate continuously.

A fuse labeled HDLP MDL protects the flasher module circuit. This fuse

is located in the underhood fuse block in the engine compartment on

the passenger’s side of the vehicle. See “Fuses and Circuit Breakers” in

the Service and Appearance Care section of your Impala owner’s

manual for more information.

When the headlamps flashing module is turned on, the module sends a

signal to the Body Control Module (BCM). The BCM alternately flashes

the stop lamps and backup lamps. Depressing the brake pedal will

override the stop lamp flashing and placing the transaxle in reverse will

override the backup lamp flashing.

When it is dark outside, the taillamps will turn on automatically. The

Center High-Mounted Stoplamp (CHMSL) will not flash and will operate

only when the regular brake pedal is pressed.
