DTC Descriptors



DTC P0562



- System Voltage Low



DTC P0563



- System Voltage High



Diagnostic Fault Information



Circuit/System Description



The transmission control module (TCM) continuously monitors the system voltage on the Ignition 1 voltage circuits. Lower than normal voltage



may be inadequate to operate the transmission control solenoids properly. Improper solenoid operation may cause erratic transmission operation,



which may result in internal damage. Theses DTC detects high or low TCM voltage for an extended period.



Conditions for Running the DTC



DTC P0562



* Ignition voltage is 8.6 volts or greater.



* Engine speed is 1200 RPM or greater.



* DTC P0563 is not set.



DTC P0563



* Ignition voltage is 8.6 volts or greater.



* DTC P0563 is not set.



Conditions for Setting the DTC



DTC P0562



The TCM detects system voltage is less than 8.6 volts for 12 seconds.



DTC P0563



The TCM detects system voltage is 18 volts or greater for 12 seconds.



Action Taken When the DTC Sets



DTCs P0562 and P0563 are Type C DTCs.



Conditions for Clearing the DTC



DTCs P0562 and P0563 are Type C DTCs.
