Handwash Sensor Error, Resistance Too High
â–¶ How to fix
- Check the sensor. - Check the supply to the sensor. - Check power supply to TCC
What you'll see
handwash tank full with No indication,warning on display for Flush tank level full.
System reaction
warning on display for Flush tank level full.
Diagnostic depth
Detection
The ECU detects the handwash tank level based on variation in resistance from this analog resistive sensor. Normal operation range of resistance is between (0 Ohms to 10000 Ohms). - Resistance on CN3-10 is above nominal value.
Possible cause
The resistance is above nominal value. - faulty sensor. - sensor supply faulty. - power supply to TCC is faulty
