Circuit/System Description

This diagnostic applies to internal microprocessor integrity conditions within the engine control module (ECM) and the throttle actuator control (TAC) system. 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. The ECM and the TAC processors are used to monitor the TAC system data. Both processors monitor the other processors data to verify that the indicated accelerator pedal position (APP) calculation is correct. The ECM performs an intrusive test in order to confirm that the APP signals are not shorted together. The ECM accomplishes this by pulling the APP sensor 2 low momentarily and looking for sensor 1 to also be pulled low.

Circuit/System Testing

  1. Observe the DTC information with the scan tool. Verify DTC P0602 00 is not set.
  2. If DTC P0602 00 is set, attempt to program the K20 Engine Control Module. Refer to Control Module References . If DTC P0602 00 resets, perform the following steps:
    3. •  Ensure that all tool connections are secure.
    •  Ensure that the programming equipment is operating correctly.
    •  Ensure the correct software and the correct calibrations are being used.
    •  Attempt to program the K20 Engine Control Module. Refer to Control Module References .
         ⇒ If DTC P0602 00 resets, replace the K20 Engine Control Module.
  3. Test the K20 Engine Control Module voltage circuits at ECM connector X1 terminals 12 and test the ground circuit at ECM connector X2 terminal 73 for the following:
    4. •  A short
    •  An open
    •  High resistance
         ⇒ If all circuits test normal, replace the K20 Engine Control Module.
