Circuit Description

Circuit A14 is a bus bar in the PDC, and connects to battery voltage. The contact side of the Automatic Shut-Down (ASD) relay connects circuit A14 and circuit A142. A 20 Amp fuse in the PDC protects circuits A14 and A142.

Circuit A14 also supplies voltage to the coil side of the ASD relay. The Powertrain Control Module (PCM) controls the ground path circuit for the coil side of the ASD relay on circuit K51. Circuit K51 connects to cavity 18 of the PCM connector.

Circuit A142 supplies voltage for the ignition coil pack through cavity 2 of the ignition coil connector. The coil pack consists of two individual coils molded together. The PCM controls the ground circuit of each coil.
- Circuit K17 is the ground circuit for the ignition coil that fires spark plugs # 1 and # 4. Circuit K17 connects to cavity 21 of the PCM and to cavity 3 of the ignition coil connector.
- Circuit K19 is the ground circuit for the ignition coil that fires spark plugs # 2 and # 3. Circuit K19 connects to cavity 1 of the PCM.
