C1046/020550

C1046/020550 - Ride-Height System; Plausibility Error

Possible Symptoms

• Lever Control dash warning
• Ride height drops or does not respond

Possible Causes

• Air Leak (Air struts, lines, fittings, etc.)
• Weak compressor (not enough air pressure)
• Valve Block (water damage, stuck valves, etc.)
• Level Sensors (loose, installed backwards, etc.)

Possible Solutions

• Check for and repair as needed any Air Leaks
• Verify compressor operation with Output Tests
• Verify Valve Block solenoids operation with Output Tests
• Check Level Sensor plausibility using Measuring Values

Special Notes

• The fault code C1046 will set if the Level Control module detects instances of uncontrolled height changes (such as due to leakage) or when the height remains unchanged despite a control request.
