P1d61 Jeep Description

This diagnostic detects if the power supply to valve actuators is shorted to ground or to battery. The diagnostic also compares this power supply to the Safety Micro Processor (SMP) power supply. When the valve actuators power supply has an electric fault or its voltage deviates from the SMP power supply, the diagnostic will be considered failing.
