* The engine speed is greater than 500 RPM.



* Ignition voltage is between 8.6-19.0 volts.



Conditions for Setting the DTC



The TCM detects 6 volts or less on the ignition 1 voltage circuit at the TCM for 1.0 second or more.



Action Taken When the DTC Sets



* DTC P2534 is a Type A DTC.



* The TCM turns OFF HSD1 and HSD2.



* The TCM turns OFF all solenoids.



* The TCM commands maximum line pressure.



* The TCM freezes transmission adaptive functions.



* The TCM commands the TCC OFF.



* The TCM allows the vehicle to operate in transmission protection mode.



* The TCM disables Tap up and Tap down functions.



Conditions for Clearing the DTC



DTC P2534 is a Type A DTC.



Diagnostic Aids



If all circuit tests are OK, ensure the transmission pass through connector and harness terminals are clean and not damaged, and the charging



system is functioning correctly.

Circuit/System Verification



1. Engine ON, accessories OFF, measure and record the battery voltage with a DMM. The battery voltage should be between 12.5-14.5 volts.



瀚慖f the voltage is not within the specified value, or the charge indicator light is ON, refer to Symptoms - Engine Electrical (See: Starting



and Charging/Testing and Inspection/Symptom Related Diagnostic Procedures/Symptoms - Engine Electrical).



2. Observe the scan tool TCM Ignition Voltage parameter. The reading should be between 12.5-14.5 volts.



3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the



conditions that you observed from the Freeze Frame/Failure Records data.
