Circuit/System Description

This diagnostic applies to internal microprocessor integrity conditions within the engine control module (ECM). This diagnostic also addresses if

the ECM is not programmed, or is programmed incorrectly.

Conditions for Running the DTC

P0601, P062B, P0630, P16F3

These DTCs run continuously when the ignition is ON.

P0602, P0603, P062F

These DTCs run at power up.

P0604

DTC P0604 runs continuously when the ignition is ON. First memory scan may take up to 30 s.

P0606

* System voltage is greater than 6 V.

* Reduced engine power is not active.

* DTC P0606 runs continuously when the above conditions are met.

P2610

* The intake air temperature is between -40 to +80掳C (-40 to +176掳F).

* 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
