DTC |
C1521/21 |
Motor Circuit Malfunction |
DESCRIPTION
The VGRS ECU drives the actuator while turning the steering wheel to set the gear ratio.
It detects the current flowing into the actuator motor driving circuit. When the VGRS ECU detects excessive current, it records the DTC, turns on the VGRS warning light, and stops VGRS operation.
