DTC P1360: Ignition Control Circuit Group B: Description

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

• Ignition 1 voltage.
• Ground.
• IC timing low reference.
• IC circuits for cylinders No. 1-8.

Each ignition coil connects directly to its spark plug via a short boot. The IC circuits transmit timing pulses from the Powertrain Control Module (PCM) to the IC modules, which triggers the coils to fire the plugs in the correct sequence. The PCM monitors each IC circuit for improper voltage levels.
