Important: This test is designed in order to test the power source for the left rear tail lamps originating from the LR PRK fuse in the underhood fuse block. Because the stop lamps and the turn signal lamps do not share the same power source, the stop lamps and the turn signal lamps may operate properly. Because the lamps all share the same ground, a ground problem may cause a complete tail lamp failure in the left rear of the vehicle. For any other symptoms refer to Exterior Lights System Check .
