Title: BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: C1417; High Power Supply Voltage Malfunction; 2018 MY Camry [03/2017 - 06/2017] |
DTC
|
C1417
|
High Power Supply Voltage Malfunction
|
DESCRIPTION
If a malfunction is detected in the power supply circuit, the skid control ECU (brake actuator assembly) stores this DTC and the fail-safe function prohibits ABS operation.
This DTC is stored when the +BS terminal voltage deviates due to a malfunction in a power supply or charging system circuit such as the battery or alternator circuit, etc.
DTC No.
