Conditions for Setting the DTC

The ECM detects one of the following failures on the IC circuit:

* An open

* A short to ground

* A short to voltage

Action Taken When the DTC Sets

DTCs P0351-P0358 are Type B DTCs.

Conditions for Clearing the DTC

DTCs P0351-P0358 are Type B DTCs.

Diagnostic Aids

* This test procedure requires that the vehicle battery has passed a load test and is completely charged. Refer to Battery Inspection/Test (See:

Starting and Charging/Testing and Inspection/Component Tests and General Diagnostics/Battery Inspection/Test).

* A high resistance condition on any IC circuit can cause an engine misfire without setting DTC P0351-P0358.

Circuit/System Verification

1. With the engine running, monitor the following ignition control (IC) circuit status parameters with a scan tool:

* Cylinder 1-8 IC Ckt. Short Gnd Test Status

* Cylinder 1-8 IC Ckt. Open Test Status

* Cylinder 1-8 IC Ckt. Short to Volts Test Status

瀚慐ach parameter should display OK.

2. With the engine running, observe the Misfire Current counters with a scan tool.

瀚慣he counters should not be incrementing.

3. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed

from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. With the engine running, monitor the Cylinder 1-8 IC Circuit Status parameters with a scan tool.
