Powertrain Control Module (Pcm): Mem-Cal: Installation

  1. Carefully align MEM-CAL pins with PCM pin holes. DO NOT press in middle of MEM-CAL. Push downward evenly on ends of MEM-CAL until retaining clips on ends of MEM-CAL snap into place.
  2. Install PCM. Reconnect negative battery cable. Turn ignition on and ground DLC terminal "B". DTC 12 should be flashed at least 4 times. If DTC 12 is not flashed at least 4 times, other codes are present. If DTC 51 is present, or if MIL stays on constantly with code(s) present, MEM-CAL is not fully seated, or is defective.
