P0563 Jeep Code - System Voltage High
Quick Answer
The Transmission Control Module (TCM) monitors the system voltage level at the TCM supply voltage terminal for the following failure conditions: - System Voltage Excessively Low - System Voltage Low - System Voltage High If the TCM supply voltage is below a threshold that is lower than the System Voltage Excessively Low threshold, the TCM will not supply power to the solenoid valves and pressure regulators. Common causes include Faulty alternator, Open or short system voltage circuit, Faulty Transmission Control Module (TCM). 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.
