Step-by-Step Instructions to Fix U1A35-62

Step 1: Replace the Faulty RLM Module

1. Identify and remove the faulty Ride Level Module (RLM).
2. Replace it with a new RLM that matches the original part number.
   • Original Module Part Number: Verify the part number from the old module.
   • New Module Part Number: Ensure the replacement module matches exactly.

Step 2: Connect Diagnostic Equipment

1. Connect the diagnostic device (e.g., Autel J2534) to the vehicle’s OBD-II port.
2. Link the device to a laptop running SDD software.

Step 3: Diagnose the Fault

1. Launch the SDD software and connect it to the vehicle.
2. Read the fault codes in the Ride Level Module (RLM).

2. Verify that the U1A35-62 error no longer appears on the dashboard.

Step 7: Calibrate the Suspension System

1. Perform a suspension calibration using measurements from all four wheels.
2. Use the SDD software to adjust and ensure accurate ride height alignment.

Step 8: Verify the Fix

1. Re-check the dashboard and diagnostic software to confirm no active fault codes.
2. Test drive the vehicle to ensure the suspension system is functioning properly and the speed limitation is removed.

Key Considerations
