How is power supplied to the Transmission Control Module?
In transmissions with electronic shift controls, power is supplied to the transmission control module through the transmission control output circuit. This circuit provides the requisite power for the transmission control module, the transmission solenoid/pressure switch assembly, and the PCM under normal operating conditions.
What should system voltage be when engine is shut off?
When the engine is shut off, you normally should have 12 volts in the system and when the engine is running, the alternator should charge the car 13.5-14.3 volts. The P0562 code means that the engine control unit recognizes a voltage of under 10 volts for 1 minute when the engine is running in the electric system.
Why does my transmission control module act weird?

What’s the low voltage on my Cummins coach?
And then underneath the warning was the system voltage displayed as 13.8V and then Theshold at 13.4V. After moving the coach forward, the warning went out. I called Cummins and they said this is an OEM issue.
Can a low voltage system cause a check engine light?
Low voltage can cause many strange and different symptoms in your car. Writing down all these symptoms would take forever, so I will list the most common symptoms of the P0562 code. Sometimes there could be a problem with the power cable to the engine control unit, and you will get no symptoms except a check engine light.
How many volts does an alternator need to charge a car?
Normally modern cars use a 12-volt system. When the engine is turned off, there should be 12 volts in the system, and when the engine is running, the alternator should charge the car with 13.5-14.3 volts. Code P0562 means that the motor control unit detects a voltage below 10 volts for 1 minute when the motor is running in the electrical system.
