ON-BOARD DIAGNOSTIC (DYNAMIC STABILITY CONTROL)
STEP
3 INSPECT STEERING ANGLE SENSOR
SIGNAL CIRCUIT FOR OPEN CIRCUIT
• Inspect continuity between DSC HU/CM
terminal (harness side) and steering angle
sensor terminal (harness side) below.
— Sensor 1: DSC HU/CM X and steering
angle sensor B
— Sensor 2: DSC HU/CM W and steering
sensor C
— Neutral: DSC HU/CM U and steering
angle sensor D
• Is there continuity?
4 INSPECT STEERING ANGLE SENSOR
SIGNAL CIRCUIT FOR SHORT TO POWER
• Turn ignition key to ON (engine OFF).
• Measure voltage between DSC HU/CM
terminal (harness side) and ground below.
— Sensor 1: DSC HU/CM X and ground
— Sensor 2: DSC HU/CM W and ground
— Neutral: DSC HU/CM U and ground
• Is voltage B+?
5 INSPECT STEERING ANGLE SENSOR
SIGNAL CIRCUIT FOR SHORT TO GROUND
• Turn ignition key to OFF.
• Inspect continuity between DSC HU/CM
terminal (harness side) and ground below.
— Sensor 1: DSC HU/CM X and ground
— Sensor 2: DSC HU/CM W and ground
— Neutral: DSC HU/CM U and ground
• Is there continuity?
6 INSPECT STEERING ANGLE SENSOR
• Inspect steering angle sensor.
(See P–44 STEERING ANGLE SENSOR
INSPECTION)
• Is it okay?
7 VERIFY TROUBLESHOOTING COMPLETED
• Clear DTC from memory.
(See P–46 Clearing DTCs
• Is same DTC present?
8 VERIFY AFTER REPAIR PROCEDURE
• Is there any other DTC present?
