### Circuit/System Description

These DTCs apply to internal microprocessor integrity conditions within the engine control module (ECM). This diagnostic also addresses if the ECM is not programmed.

### Conditions for Running the DTC

#### P0602, P0605, P0606, P0607, P060A, P060B, P0610, P061A, and P061C

• | The ignition is ON.

• | The DTCs run continuously once the above condition is met.

#### P062B

• | The engine is running.

• | The DTC runs continuously once the above condition is met.

### Conditions for Setting the DTC

#### P0602 and P0610

The ECM detects that programming is incomplete for greater than 1 s.

#### P0605, P0606, P0607, P060A, P060B, P061A and P061C

The ECM detects an internal condition for greater than 1 s.

#### P062B

The ECM detects an internal fuel injector condition once per camshaft revolution.

#### P062F

The ECM detects an internal EEPROM failure.

### Circuit/System Testing

#### P0602 or P0610

Program the ECM. If DTC P0602 or P0610 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 (ECM).

⇒ | If DTC P0602 sets, replace the K20 Engine Control Module (ECM).

#### P0605, P0606, P0607, P060A, P060B, P061A, P061C, P062B or P062F

1. Observe the Freeze Frame/Failure Records with a scan tool.
2. Clear the DTCs with a scan tool.
3. Ignition OFF for 30 s.
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.

⇒ | If DTCs P0605, P0606, P0607, P060A, P060B, P061A, P061C, P062B or P062F failed this ignition, replace the K20 Engine Control Module (ECM).

### Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
