### Circuit/System Verification

1. Ignition ON, observe the DTC information with a scan tool. DTC P0602, P0610, P0614, P0630, P160D, P160E, and P161F should not set.

⇒ | If a DTC failed this ignition, program the K20 ECM. Refer to Control Module References. If the DTC resets, replace the K20 ECM.

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.

### Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
