There is NO Signal Relay
It is controlled thru the LCM (Lighting control module)
Prior to removal of the module, it is necessary to upload module configuration information to a scan tool. This information needs to be downloaded into the new module once installed
When the multifunction switch is placed in the LH or RH TURN positions, the multifunction switch routes voltage to the LH or RH turn signal lamps. The LCM then cycles the voltage on and off approximately 80 times per minute. If a front or rear turn bulb is inoperative, the LCM cycles the voltage on and off approximately 160 times per minute.
Use of Dealer Scan Tool is needed
apprx 1 hour labor
