"HOLD" INDICATOR LIGHT FLASHES



DESCRIPTION

On some 1993 RX-7 vehicles, the torque reduction control fail diagnostic system may start working without any failure and cause the "hold" light to flash while the vehicle is running.

Beginning May 11, 1992, the circuit logic of the torque reduction control has been changed to eliminate this possibility.
