Circuit Description

Output Driver Modules (ODMs) are used by Powertrain Control Module (PCM) to turn on current driven devices that are needed to control various engine and transaxle functions. Each ODM can control up to 7 separate outputs by grounding the device that PCM is commanding on. ODMs can diagnose each output circuit individually.

Conditions for setting DTC:

• Ignition is on.
• Improper voltage level detected on ODM B output No. 2 (high speed fan relay driver circuit).
• Conditions present for at least 30 seconds.
