FLASHER MODULE OPERATION
The Turn Signal/Hazard Warning Flasher is a module providing turn signal, hazard warning functions and has been designed with internal relays
to take advantage of low current switching requirements in the vehicle. It is plugged into the Junction Block at position 4 where all wiring
associated with its operation is terminated. The Junction Block is adjacent to and left of the steering column of the vehicle.
To gain access to the device, remove the lower steering column cover and knee blocker.
The combination flasher may be operated in its hazard warning mode either with or without the ignition circuit being active. However, in order to
operate in the turn signal mode, the ignition circuit must be completed to the module.
While the combination flasher is idle, there is no current drawn through the module. The device does not become active until a signal ground
circuit is supplied to either of the turn signal inputs or the hazard warning input.
Typical flash rate for the flasher is 90 flashes per minute. When a lamp is burnt out for a given side of the vehicle or a wire is open to a lamp, the
flash rate will increase to 180 flashes per minute when in the turn signal mode. When in the hazard warning signal mode the flash rate remains at
90 flashes per minute.
Turn signal inputs that actuate the flasher are low current grounds, each drawing a maximum of 300 mA and are provided to the flasher through
the Junction Block from the multi-function switch that is mounted to the steering column. The hazard warning signal input is a low current ground
drawing a maximum of 600 mA through the multi-function switch.
