SEO 6J7 provides a high-beam headlamps flashing module, rear
lamps flashing control wire for a customer-furnished switch to turn the
module on or off. The flasher control wire is coiled under the center of
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 below the passenger’s
side front headlamp and forward of the passenger’s side front wheel.
The module is connected to an inline connector in the forward lamp
harness. 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.
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 transmission in reverse
will override the backup lamp flashing.
During daylight conditions, the Daytime Running Lamps (DRL) are
automatically turned off whenever the headlamps flashing 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 20-amp fuse protects the flasher module circuit. This fuse is located
in the underhood fuse block in the engine compartment on the driver’s
side of the vehicle. See “Fuses and Circuit Breakers” in the Service and
Appearance Care section of your Tahoe owner’s manual for more
information.
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.
