Description:

This error code, EPC 524234.04, is generated when the control unit registers no enable pressure (pressure below 50 kPa; 0.5 bar; 7.3 psi). This indicates a circuit problem at the enable pressure sensor (B105) or an enable pressure that is too low.

Reaction:

When this error is detected, the system may interpret the enable pressure as too low, 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 low 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 low pressure. Investigate the hydraulic system and components to rule out any underpressure 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 underpressure issues.
