DTC Descriptors



DTC P0562



- System Voltage Low



DTC P0563



- System Voltage High



DTC P2534



- Ignition 1 Switch Circuit Low Voltage



Diagnostic Fault Information



Circuit/System Description



The transmission control module (TCM) within the control solenoid valve assembly continuously monitors the system voltage on the ignition



voltage circuit. 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. These DTCs detect high or low TCM voltage for an extended



period.



Conditions for Running the DTC



P0562



* Ignition voltage was 6.0 volts or greater and has not dropped below 2.0 volts.



* Engine speed is 1,200 RPM or greater.



P0563



Ignition voltage was 6.0 volts or greater and has not dropped below 2.0 volts.



P2534



* The engine is running.



* Ignition voltage was 6.0 volts or greater and has not dropped below 2.0 volts.



Conditions for Setting the DTC



P0562



The TCM detects system voltage is 11 volts or less for 4 seconds.



P0563



The TCM detects system voltage is 18 volts or greater for 10 seconds.
