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.



Circuit/System Testing



1. Ignition OFF, disconnect the X1 16-way harness connector at the T12 automatic transmission assembly.



2. Ignition OFF, test for less than 5 ohms on the vehicle harness connector X1 terminal 5 and ground at the transmission case.



瀚慖f greater than then specified valve, test the ground circuit for an open/high resistance.



3. Ignition ON, verify that a test lamp illuminates at connector X1 vehicle harness side and the following terminals:



* Terminal 4 and ground at the transmission case



* Terminal 12 and ground at the transmission case



瀚慖f the test lamp does not illuminate on any circuit, test the ignition or B+ circuit for a short to ground or an open/high resistance.



4. If all circuits test normal, replace the Q8 control solenoid valve assembly.

DTC Descriptors



DTC P2544



- Transmission Torque Request Circuit



Circuit/System Description



To improve shift feel, the transmission control module (TCM) may request that the engine control module (ECM) reduce engine torque during shift



events. When such a request is received, the ECM responds by retarding the injection timing and notifying the TCM that the request has succeeded.



If the ECM is unable to comply with the request, the ECM sends the TCM a message that the request has failed.



The torque reduction request is sent to the ECM through GMLAN.



Conditions for Running the DTC



* The ignition is ON for greater than 3 seconds.



* The ignition voltage is between 10-18 volts.



* The DTCs run continuously once the above condition is met for greater than 10 mS.



Conditions for Setting the DTC



The ECM detects an invalid signal from the TCM for greater than 1 second, or a cumulative of 10 seconds.



Action Taken When the DTC Sets



DTC P2544 is a Type C DTC.



Conditions for Clearing the DTC



DTC P2544 is a Type C DTC.

Image
 BMW (Benz-Wesbach) is a well-known and respected luxury brand in the European automotive market, particularly for sports cars like the M5. However, unlike some other car manufacturers, BMW has not primarily focused on its formula racing or sport engineering heritage. Instead, the BMW M series has been a strong seller due to their sportiness, reliability, and aesthetic appeal. If you're referring to BMW's M5 sedan **and touring variant** with performance parts, here are some key points to consider: 1. **Performance Improvement**:     - BMW’s sports cars, including the M5 models, have improved over previous iterations. The 3.0 liter straight-6 power plant in the M5 has seen improvements like a new torque vectoring system and increased engine robustness.
