B1455: Wiper Washer Fluid Lamp Circuit Open

Definition

The OBD2 code B1455 indicates that there is an open circuit in the wiper washer fluid lamp, meaning the system is not detecting the lamp's operation properly, which could be due to a wiring issue or a faulty component

Common causes

Faulty wiper washer fluid lamp
Open circuit or broken wiring
Poor connection or corroded terminals
Malfunctioning body control module (BCM)
Blown fuse related to the washer fluid lamp circuit

Common misdiagnoses

Faulty wiper washer fluid level sensor
Wiring issues or shorts in the circuit
Malfunctioning body control module (BCM)
Blown fuse related to the washer system
Incorrectly installed or damaged washer fluid reservoir
Faulty dashboard indicator or gauge
Issues with the wiper control switch

Troubleshooting steps

1. Visual Inspection
2. Check the wiring and connectors associated with the washer fluid level sensor. Look for any signs of damage, corrosion, or loose connections
3. Inspect the washer fluid reservoir for any cracks or leaks that could affect the sensor
4. Check the Washer Fluid Level
5. Ensure that the washer fluid reservoir is filled to the appropriate level. If the fluid is low, it may trigger the code
6. Test the Washer Fluid Level Sensor
7. Locate the washer fluid level sensor, which is typically located in the washer fluid reservoir
8. Disconnect the sensor and use a multimeter to check for continuity. If there is no continuity, the sensor may be faulty and needs to be replaced
9. Check the Circuit
10. With the sensor disconnected, use a multimeter to check for voltage at the connector. If there is no voltage, trace the wiring back to the vehicle's body control module (BCM) or instrument cluster to identify any breaks or shorts in the circuit
11. If there is voltage but the sensor is not functioning, the sensor itself may be defective
12. Inspect the Body Control Module (BCM)
13. If all wiring and the sensor are in good condition, the issue may lie within the BCM. Check for any fault codes related to the BCM and consider reprogramming or replacing it if necessary
14. Clear the Code
15. After performing repairs or replacements, clear the code using an OBD-II scanner and take the vehicle for a test drive to see if the code returns
16. Consult the Service Manual
17. Refer to the vehicle's service manual for specific wiring diagrams and troubleshooting procedures related to the washer fluid lamp circuit
18. Seek Professional Help
19. If the issue persists after performing these steps, it may be best to consult a professional mechanic or technician who has experience with your specific vehicle make and model. By following these steps, you should be able to identify and resolve the issue related to the B1455 code
