Typical Scan Tool Data
Circuit/System Description
The transmission control module (TCM) samples the system voltage on the Ignition 1 voltage circuit every 0.1 seconds. 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.
Conditions for Running the DTC
The TCM is communicating on the GMLAN serial data bus.
Conditions for Setting the DTC
The TCM detects less than 2 volts on the IGN voltage circuit at the TCM for greater than 10 seconds.
Action Taken When the DTC Sets
* P2534 is a Type A DTC.
* The TCM turns OFF all solenoids.
* The TCM commands maximum line pressure.
* The TCM freezes transmission adaptive functions.
Conditions for Clearing the DTC
P2534 is a Type A DTC.
Diagnostic Aids
* Ensure the transmission pass through connector and harness terminals are clean and not damaged, and the charging system is functioning
correctly.
* The transmission 24-way inline harness connector must be disconnected prior to disconnecting the transmission 16-way inline harness
connector
