P0220, P0222, P0223, P0335, P0336, P0606, P0641, P0651, P1516, P2101, P2120, P2122, P2123, P2125, P2127, P2128, P2135, P2138, and

P2176 are not set.

* When DTC P0315 is set, the engine speed must be more than 1,000 RPM.

* Engine run time is more than 2 crankshaft revolutions.

* The engine speed is between 375-5,600 RPM.

* The ignition voltage is between 9-18 volts.

* The engine coolant temperature (ECT) is between -7 and +130掳C (+19 and +266掳F).

* When the startup ECT is colder than -7掳C (+19掳F), this diagnostic will be delayed until the ECT is warmer than +21掳C (+69掳F).

* The fuel level is more than 10 percent.

* The ECM is not in fuel shut-off, or decel fuel cut-off mode.

* The electronic brake control module (EBCM) and the traction control system (TCS) are not active or detecting rough road.

* An automatic transmission shift with a throttle position more than 95 percent is not occuring.

* The power management is not active.

* Excessive drive wheel slip is not detected.

* The power take-off (PTO) is disabled, where applicable.

* The cylinder deactivation is not in progress, where applicable.

* DTCs P0300-P0308 run continuously when the above conditions are met.

Conditions for Setting the DTC

DTC P0300

The ECM is detecting a crankshaft speed change indicating a random misfire is occuring that exceeds mandated emission level standards or is at

catalytic converter damaging levels.

DTC P0301, P0302, P0303, P0304, P0305, P0306, P0307, or P0308

The ECM is detecting a crankshaft speed change indicating a single cylinder misfire is occuring that exceeds mandated emission level standards or

is at catalytic converter damaging levels.

Action Taken When the DTC Sets

* DTCs P0300-P0308 are Type B DTCs.

* When the MIL is flashing the fuel injector may be disabled for the misfiring cylinder to protect the catalytic converter.

* Depending on the conditions that set the DTC, the engine may go into Open Loop.

Conditions for Clearing the MIL/DTC

* DTCs P0300-P0308 are Type B DTCs.

* The DTC must run and pass under the same operating conditions that were present when the DTC failed.

Diagnostic Aids

* Ensure that each fuel injector is connected to the proper fuel injector harness connector.

* A misfire may only occur when the engine is operating under a load or when the engine is cold.

* A high resistance condition on any ignition control (IC) circuit can cause an engine misfire P0300-P0308 DTC to set without setting an IC

circuit P0351-P0358 DTC.

* 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 misfire DTC could be caused by an excessive vibration from sources other than the engine. Inspect the following for possible sources of

vibration:

- A tire or wheel that is out of round or balance

- Variable thickness brake rotors

- An unbalanced drive shaft

- Certain rough road conditions

- A damaged accessory drive component or belt

- A damaged reluctor wheel

- The Crankshaft Position System Variation Learn procedure may need to be performed.

DTC Descriptor

DTC B1023 00

- Integral Switch Malfunction

Circuit/System Description

The vehicle theft deterrent subsystem provides the capability to lock or unlock the steering electrically. The steering column lock control module is

allowed to unlock when power mode transitions to a non off power mode and an authenticated driver identification device is present. Once the

column is unlocked, a crank request can be allowed.

Conditions for Running the DTC

* The ignition is in OFF, ACCESSORY or RUN position.

* The system voltage is between 9-16 V.

Conditions for Setting the DTC

The steering column lock control module detects an internal sensor malfunction resulting in lock status of invalid to be transmitted on serial data.

Action Taken When the DTC Sets

* DTC B1023 is stored in memory.

* The driver information center displays the service column lock system warning message.

* The steering column lock indicator is ON.

Conditions for Clearing the DTC

* No steering column lock control module internal sensor malfunction so lock status of valid is transmitted on serial data.

* The condition for setting the DTC is no longer present.
