Details of the b1455 OBD Code
B1455 indicates a fault in the HVAC control module communication circuit.
OBD code B1455 means Wiper Rear Motor Speed Circuit Failure.
This code is triggered by the Body Control Module (BCM) when it detects a malfunction in the rear wiper motor speed circuit.
The BCM monitors the voltage signals from the rear wiper motor to determine the speed of the motor.
If the BCM detects a discrepancy or no signal from the rear wiper motor, it will set code B1455. This code indicates a problem with the rear wiper motor speed circuit, which could be caused by issues such as a faulty rear wiper motor, wiring problems, or a defective BCM.
Mechanic’s Tech Notes
Code B1455 indicates a fault in the driver’s door key cylinder switch circuit.
OBDII code B1455 indicates a communication error with the TCM (Transmission Control Module).
To diagnose, check TCM power and ground using a multimeter.
Verify TCM response over the CAN network with a scan tool.
Visually inspect wiring harness and connectors for damage, and check connector pins for issues like being broken, bent, pushed out, or corroded.
Reflashing the TCM may be necessary.
This process helps pinpoint the root cause of the communication fault and ensures a proper fix.
