* DTCs P0111, P0112, P0113 are not set.

* DTC P2610 runs on ECM power down.

Conditions for Setting the DTC

The ECM detects an internal failure or incomplete or incorrect programming.

Action Taken When the DTC Sets

* DTCs P0601, P0602, P0603, P0604, P0606, P062B, P062F, P0630 and P16F3 are Type A DTCs.

* DTC P2610 is a Type B DTC.

Conditions for Clearing the DTC

* DTCs P0601, P0602, P0603, P0604, P0606, P062B, P062F, P0630 and P16F3 are Type A DTCs.

* DTC P2610 is a Type B DTC.

Diagnostic Aids

Low voltage or a momentary loss of power or ground to the ECM may cause a DTC to set. Verify for the following:

* The battery cables are clean and tight, and the battery is fully charged-Refer to Battery Inspection/Test (See: Starting and Charging/Testing

and Inspection/Component Tests and General Diagnostics/Battery Inspection/Test).

* The ECM ground circuits do not have an open or high resistance

* The ECM power circuits do not have an open, short to ground, or high resistance

Circuit/System Verification

1. Observe the DTC information with a scan tool. DTC P0601, P0602, P0603, P0604, P0606, P062B, P062F, P0630, P16F3, or P2610 should

not set.

2. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

1. Ignition ON, clear the DTC information with a scan tool.

2. Observe the scan tool DTC information. Verify that DTC P0602 or P0630 does not set.

瀚慖f DTC P0602 or P0630 failed this ignition, reprogram the K20 ECM. Refer to Control Module References (See: Testing and

Inspection/Programming and Relearning). If the DTC resets, replace the K20 ECM.

3. Observe the DTC information with a scan tool. Verify that DTC P0601, P0603, P0604, P0606, P062B, P062F, P16F3, or P2610 does not set.
