05 Internal Fault (EEPROM)

05 Internal Fault (EEPROM)

Possible Cause(s) of Fault:
- Terminal 30 not activated
- Memory cell defective
- EMC scatter

Storage Condition(s):
- At ignition off, data is written in the EEPROM area.
- With ignition on, the data in the memory is checked. In the case of implausibility of the EEPROM data, this fault entry is made.
- If there is no power supply via terminal 30, it can occur that the data transmission cannot be performed completely.
- If memory cells are defective, implausibilities can result.
- Note: This fault is frequently a secondary fault when terminal 30 was interrupted.

Troubleshooting Procedure:
- Check power supply to terminal 30
- Clear fault memory, switch ignition off/on and check whether the fault is entered again
- Yes: replace steering angle sensor
- No: ignore fault, as it is likely that EMC scatter or a temporary power supply interruption was the cause

Note: After replacing the steering angle sensor, it must first be coded and then calibrated using the ABS/DSC diagnostic program.
