5E20
Moderate5E20 — Internal Fault in Hydraulic Pressure Sensor (DSC)
Description
What the Code Means
Code 5E20 points to a plausibility error in the steering angle sensor (SZL). The sensor sits in the steering column and sends the steering angle to the DSC module. The fault sets when the sensor signal disagrees with other sensors, such as the yaw rate sensor.
Symptoms
Symptoms
- DSC indicator is on
- Cruise control doesn't work
- Adaptive headlights don't work
- Steering wheel may be off-center from the straight-ahead position
Causes and fixes
Diagnostics and Repair
Step 1
Read the fault codes with ISTA.
Step 2
Check the SZL calibration through ISTA (service function “Steering Angle Sensor Calibration”).
Step 3
If calibration doesn't fix it, replace the SZL (OEM 61319354048).
Step 4
After replacement, run the DSC initialization.
Possible secondary damage
Related Problems
A faulty SZL can cause DSC (Dynamic Stability Control) to misbehave, especially during sharp maneuvers. The steering column control module (SZL) can also fail from worn contact traces.
