Description:

This error code, EPC 524234.03, is generated when the control unit registers an enable pressure above 2000 kPa (20 bar; 290 psi). This indicates a circuit problem at the enable pressure sensor (B105) or an excessive enable pressure.

Reaction:

When this error is detected, the system may interpret the enable pressure as too high, potentially affecting the transmission operation and overall vehicle performance.

Recommendations:

Inspect Enable Pressure Sensor (B105):

• Check the condition and functionality of the enable pressure sensor. Replace the sensor if it is found to be defective.

Verify Pressure Readings:

• Use diagnostic tools to measure the actual pressure to confirm if the pressure is genuinely too high or if it is a false reading from the sensor.

Inspect Wiring and Connections:

• Inspect the wiring and connections to the enable pressure sensor for any signs of damage, loose connections, or corrosion. Repair or replace as necessary.

Check for System Malfunctions:

• Ensure that there are no system malfunctions causing excessive pressure. Investigate the hydraulic system and components to rule out any overpressure situations.

Reset and Test System:

• After addressing the issues, reset the system and monitor the enable pressure to ensure it operates correctly and that the error code does not reoccur.

Note:

Maintaining accurate pressure readings is crucial for the proper functioning of the transmission system. Regular inspections and maintenance of the pressure sensor and hydraulic system help prevent overpressure issues.
