Circuit/System Verification

P0602

Program the ECM. If DTC P0602 sets after programming, perform the following steps:

    • Ensure that all tool connections are secure.
    • Ensure the programming equipment is operating correctly.
    • Ensure the correct software and the correct calibration is used.
    • Attempt to program the K20 engine control module.
       ⇒If the DTC resets, replace the K20 engine control module.

P0601, P0604, P0606, P0607, P060A-P061D, P061A, or P2610

  1. Observe the Freeze Frame/Failure Records with a scan tool.
  2. Clear the DTCs with a scan tool.
  3. Ignition OFF for 30s.
  4. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records.
    5. ⇒If the DTCs reset, replace the K20 engine control module.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the repair.
