Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit Description
The Output Driver Modules (ODM) are chips that are inside the Powertrain Control Module (PCM). The ODMs provide grounded outputs that control devices. Each output has an internal feedback circuit that connects to the PCM microprocessor. The 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.
