Circuit Description
Output driver modules (ODM) are chips that are inside the powertrain control module (PCM). ODMs provide grounded outputs that control devices. Each output has an internal feedback circuit that connects to the PCM microprocessor. ODM 4 determines if the voltage or the current may cause damage to the PCM. The PCM monitors voltage through the Ignition 1 input. Any incorrect current that is on a circuit to the ODM will cause the ODM to report this DTC.
Conditions for Running the DTC
The ignition is ON.
Conditions for Setting the DTC
| • | The ODM has detected a voltage more than 33 volts. |
| • | Excessive current is detected on any circuit to the ODM. |
| • | The 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
An over-charging condition may set this DTC. Refer to Diagnostic System Check - Engine Electrical in Engine Electrical.
Thoroughly inspect any circuitry that is suspected of causing the intermittent complaint. Repair the circuits as necessary. Refer to Intermittent Conditions .

Do any parameters indicate a fault present? | Go to Step 4 | Go to Step 5 |
4 | Test for a short to voltage on the circuit to the component that indicated a fault. 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 | -- |
6 |
Does the scan tool indicate that the diagnostic Passed? | Go to Step 7 | Go to Step 2 |
7 | Does the scan tool display any additional undiagnosed DTCs? | System OK | |
