| Title: POWER ASSIST SYSTEMS: POWER STEERING SYSTEM (for Gasoline Model (for Hatchback)): C1513; Torque Sensor Deviation Excessive; 2019 - 2020 MY Corolla Corolla Hatchback GR Corolla [06/2018 - 09/2019] | ||

DTC |
C1513 |
Torque Sensor Deviation Excessive |
DESCRIPTION
The power steering ECU with motor assembly supplies a voltage of 5 V to the torque sensor (electric power steering column sub-assembly) and monitors the voltage value of the Hall IC inside the torque sensor (electric power steering column sub-assembly) which changes in response to changes in the magnetic flux density (steering torque) detected by the Hall IC, and calculates the assist torque.
The Hall IC is a duplex system, and the power steering ECU with motor assembly monitors the total value of TRQ1 (Hall IC 1) voltage and TRQ2 (Hall IC 2) voltage to detect malfunctions in the torque sensor (electric power steering column sub-assembly).
While DTC C1513 is detected, power assist is stopped due to fail-safe operation.
