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.
