The flow in steering circuit is too low.
• Check the amount of fluid in the reservoir. • Check connectors and wiring running from the flow sensor. • Check the flow sensor. • Check hoses and pipes. • Check the EHS unit.
What you'll see
•The steering system may not work properly (as long as the fault is present). • A red warning ”Steering fault” will be shown in the instrument cluster.
System reaction
Red Steering failure
Diagnostic depth
The test is only performed if the pump is ON, i.e. PWM output duty cycle is not equal to 25% (pump ON) 1. The DTC is set to active if the sensor indicates low flow AND vehicle speed is > 10 km/h for 100 ms even though the pump is on. 2. The DTC is set to active if the sensor indicates low flow AND vehicle speed is <= 10 km/h for 2000 ms even though the pump is on. 1. The DTC is set to inactive if the sensor indicates high flow AND vehicle speed is > 10 km/h for 200 ms while the pump is on. 2. The DTC is set to inactive if the sensor indicates high flow AND vehicle speed is <= 10 km/h for 2000 ms while the pump is on. The DTC is not set in the following cases: • system voltage is below 22V • system voltage is above 32V
• Low flow in steering circuit. • Faulty flow sensor. • Defect connectors or wiring. • Leakage in hoses or pipes. • Mechanical or electrical fault in the EHS unit. • Leakage in hoses or pipes.
