P1544 Toyota Code
The P1544 diagnostic trouble code (DTC) refers to a potential malfunction in the ERS (Electronic Range Select) off switch circuit. This code indicates that there is an issue with the circuit responsible for controlling the ERS off switch in the vehicle. The ERS system allows drivers to manually select and control the gear range in vehicles equipped with automatic transmissions. When the circuit malfunctions, it can lead to the inability to engage or disengage the ERS off mode. This may result in a loss of control over the gear selection and affect the vehicle’s performance. To address the P1544 DTC, it is recommended to have the vehicle inspected by a professional technician who can diagnose the specific cause of the circuit malfunction and repair or replace any faulty components to restore proper functionality of the ERS off switch circuit.
