TSC 523951.15 – Pressure Relief (TLS), Bottom Position is Not Reached
TSC 523951.15 (TSC )
Code: 523951.15
Shortcode:
Description:
This diagnostic trouble code, TSC 523951.15, is triggered when the TLS front-wheel drive axle does not reach its bottom position within 60 seconds in the pressure relief mode. Potential causes include:
- A problem in the circuit of the TLS position sensor (B53).
- A problem in the circuit of the TLS pressure reduction solenoid valve (Y69).
- A problem in the hydraulic circuit.
Reaction:
When this error occurs, the TLS front-wheel drive axle may not lower properly, leading to potential operational issues and safety concerns.
Recommendations:
Inspect TLS Position Sensor:
- Check Sensor Circuit:
- Verify the wiring and connections of the TLS position sensor B53.
- Repair or replace any faulty components in the sensor circuit.
Inspect Solenoid Valve for Pressure Reduction:
- Check Solenoid Valve Circuit:
- Ensure that the solenoid valve Y69 is functioning correctly.
- Repair or replace any faulty components in the solenoid valve circuit.
Inspect Hydraulic Circuit:
- Check for Hydraulic Issues:
- Inspect the hydraulic circuit for any signs of blockages, leaks, or other issues.
- Repair any identified problems in the hydraulic circuit.
Note:
Ensuring proper operation of the TLS front-wheel drive axle’s pressure relief function is essential for safety and performance. Regular inspections and maintenance of the TLS position sensor, solenoid valves, and hydraulic circuit are crucial to prevent issues.
