Circuit Description
The output driver module (ODM) is a control chip inside of the powertrain control module (PCM). The PCM contains multiple ODMs. ODMs provide grounded output control of devices. Each ODM output has an internal feedback circuit that connects to the PCM microprocessor. The PCM monitors voltage through the ignition 1 voltage circuit. Excessive voltage or current may cause damage to the PCM. If ODM A detects excessive current or voltage on an output control circuit, this diagnostic trouble code (DTC) will set.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
| • | ODM A has detected a voltage greater than 26.5 volts. |
| OR |
| • | Excessive current is detected on any circuit to ODM A. |
| • | The above conditions are present for 30 seconds. |
Action Taken When the DTC Sets
| • | The control module stores the DTC information into memory when the diagnostic runs and fails. |
| • | The malfunction indicator lamp (MIL) will not illuminate. |
| • | The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Failure Records. |
| • | The driver information center, if equipped, may display a message. |
Conditions for Clearing the DTC
| • | A current DTC Last Test Failed clears when the diagnostic runs and passes. |
| • | A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic. |
| • | Clear the DTC with a scan tool. |
Diagnostic Aids
| • | A condition with the charging system may cause this DTC to set. Refer to Diagnostic System Check - Engine Electrical in Engine Electrical. |
| • | For an intermittent condition, refer to Intermittent Conditions . |

1 | Did you perform the Diagnostic System Check-Engine Controls? | Go to Step 2 | |
2 | Is DTC P0560 set? | Go to Diagnostic System Check - Engine Electrical in Engine Electrical | Go to Step 3 |
3 | Observe the Output Driver Data List with a scan tool. Do any parameters indicate a fault present? | Go to Step 4 | Go to Step 5 |
4 | Test for a short to voltage on the control circuit of the component that indicated a fault. Refer to Testing for a Short to Voltage in Wiring Systems. Did you find and correct the condition? | Go to Step 6 | Go to Step 5 |
5 | Replace the PCM. Refer to Powertrain Control Module Replacement . Did you complete the replacement? | Go to Step 6 | -- |

Does the DTC fail this ignition? | Go to Step 2 | Go to Step 7 |
7 | Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed? | System OK | |
