DTC P1359: Ignition Control Circuit Group "A": Description

There are 2 separate ignition module assemblies, with 1 assembly for each bank of cylinders. Each assembly contains an Ignition Control (IC) module and 4 ignition coils. Each IC module consists of the following circuits:

• The ignition 1 voltage circuit.
• The ground circuit.
• The IC timing low reference circuit.
• The IC control circuits for cylinders 1-8.

Each ignition coil connects directly to its spark plug via a short boot. The IC control circuits transmit timing pulses from the Powertrain Control Module (PCM) to the IC modules, which trigger the coils to fire the plugs in the correct sequence. The PCM monitors each IC control circuit for improper voltage levels. If an open or short to voltage occurs in the IC control circuit group for the #1, #4, #6 and #7 cylinder, DTC P1360 sets.
