P1CC7 Fiat Code - Low Battery Voltage-Main Micro Processor Supply Shorted To Ground Or Open

Quick Answer

This diagnostic detects if the power supply to Main Micro Processor (MMP) is too low with three different tests relative to different vehicle operating conditions. Common causes include Low Battery Charge, Faulty Transmission Controller Module (TCM), Transmission Controller Module (TCM) harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1CC7 Fiat Description

This diagnostic detects if the power supply to Main Micro Processor (MMP) is too low with three different tests relative to different vehicle operating conditions. The MMP power supply is tested outside the engine cranking mode (because in this condition a brief reduction of power supply may be possible). The first check: the Transmission Controller Module (TCM) compares the MMP power supply with minimum threshold values. When the actual value of power supply is below its minimum boundary the diagnostic will be considered failing. The second check: the TCM verifies the MMP power supply is not lower than a threshold for more than an amount of time after the engine cranking mode is finished plus a time delay. The third check: the TCM verifies the MMP power supply is not lower than a threshold for more than an amount of time after the engine cranking mode is finished plus a time delay only when the hydraulic pump is on for more than a time and the pump temperature is lower than a value.
