Circuit Description

Output Driver Modules (ODM) are used by PCM to turn on current-driven devices needed to control various engine and transaxle functions. Each ODM can control up to 7 outputs, including fan 2 relay, by supplying ground to device PCM is commanding on. ODMs can diagnose each circuit individually. If ODM "B" output 2 (fan 2 relay driver circuit) detects an improper voltage level, P1652 is set.

Conditions required to set DTC are:

• Ignition is on.
• An improper voltage level has been detected on fan 2 relay driver circuit.
• Listed conditions present for greater than 30 seconds.
