Diagnostic Fault Information

Always perform the Diagnostic System Check - Vehicle , prior to using this diagnostic procedure.

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.

The ECM monitors its ability to read and write to the memory. It also monitors a timing function.

Circuit/System Testing for the DTC

Observe the DTCs with the scan tool.

⇒	If DTC P0602 is set, attempt to program the ECM before replacing the ECM. Refer to Service Programming System (SPS) Notice .

⇒	If DTC P0602 resets, replace the ECM.

Test the voltage and ground inputs to the ECM for the following:

•	A short to ground.

•	An open/high resistance.

⇒	If all circuits test OK, replace the ECM.
