Possible Causes:

Battery Voltage Issues: EPS systems are highly sensitive to voltage fluctuations. A weak o r failing battery can cause power assist to fail.
Faulty Sensors: Malfunctioning sensors in the EPS system can lead to loss of power steering assist.
EPS Motor Failure: The EPS motor can wear out o r fail, especially in older models.

Diagnosis and Common Error Codes:

Common error codes related to EPS issues include C1535, C1541, o r C1555 which indicate problems with the EPS motor, sensor, o r steering angle sensor.

Diagnosis and Solutions:

Diagnosis:
Check the battery’s voltage and alternator output to ensure stable voltage.
Use an OBD-II scanner to check for EPS fault codes.
Fixes:
Battery and Alternator Check: Ensure that the battery and alternator are functioning properly, as low voltage can trigger EPS issues.
Scan for Fault Codes: Use an OBD-II scanner to identify any faults in the EPS system.
System Reset: Reset the EPS system by disconnecting the battery for a few minute
