What Does U0435 Mean?
The receiving control module has detected invalid data from the rear power steering control module. This affects vehicles with rear-wheel steering or four-wheel steering systems where the rear axle steering angle is electronically controlled.
Safety Warning
Rear steering functionality will be disabled, affecting vehicle maneuverability at low speeds and stability at high speeds. Vehicle handling will differ significantly from normal operation.
Common Causes
30%
Rear power steering control module internal failure or software error
25%
Faulty rear steering angle sensor or position sensor providing incorrect feedback
20%
CAN bus communication fault or damaged wiring to rear steering module
15%
Mechanical binding or failure in rear steering actuator affecting sensor readings
10%
Power supply issues or poor ground connection at rear steering module
Diagnostic Steps
1
Step 1: Check for additional DTCs in rear steering module and related systems; verify rear steering system power and ground circuits are within specifications
2
Step 2: Inspect rear steering module connector and wiring harness for damage, corrosion, or loose connections
3
Step 3: Monitor live data from rear steering angle sensor while manually moving rear wheels (if possible with engine off); verify smooth, proportional readings
4
Step 4: Check CAN bus communication between rear steering module and main control modules; verify network integrity
5
Step 5: Perform rear steering system initialization/calibration procedure per manufacturer specifications; if fault persists, test rear steering actuator operation and replace faulty components
Estimated Repair Cost
$400 - $2,500
