Check the following items with the vehicle stopped
Is air pressure and size of tires proper?
Is the specified part used for the steering wheel?
Is control unit a genuine part?
Are there any fluid leakage from steering gear assembly, power steering oil pump, and hydraulic pipes,
etc? Refer to PS-8, "
POWER STEERING FLUID" .
Is the fluid level proper? Refer to PS-8, "POWER STEERING FLUID" .
Is the wheel alignment adjusted properly? Refer to FSU-19, "SERVICE DATA AND SPECIFICATIONS
(SDS)" (2WD), FSU-36, "SERVICE DATA AND SPECIFICATIONS (SDS)" (AWD).
Are there any damage or modification to suspension or body resulting in increased weight or altered
ground clearance?
Check each link installation condition of suspension and axle.
Check each connector connection condition.
Check the following items while driving the vehicle
Check conditions when the malfunction occurred (5W 1H).
Is the engine condition normal?
Basic InspectionNGS000E2
POWER SUPPLY CIRCUIT TERMINAL LOOSENESS AND BATTERY
Check battery terminals for looseness on both positive and negative ones and ground connection. Also make
sure that battery voltage does not drop.
Inspection: Power Steering Control Unit Power Supply Circuit and GroundNGS000E3
1. CHECK POWER STEERING CONTROL UNIT CONNECTOR
Turn ignition switch OFF, disconnect power steering control unit harness connector, and check terminal for
deformation, disconnection, looseness, etc.
OK or NG
OK >> GO TO 2.
NG >> Connector terminal connection is loose, damaged, open, or shorted. Repair or replace the termi-
nal.
2. CHECK POWER STEERING CONTROL UNIT GROUND CIRCUIT
Disconnect power steering control unit harness connector M8, and
then check continuity between power steering control unit harness
connector M8 and ground.
OK or NG
OK >> GO TO 3.
NG >> Ground circuit open or shorted. Repair or replace any
inoperative parts. Terminal 2 – Ground : Continuity exist.

Basic InspectionNGS000EO
BASIC INSPECTION 1: POWER SUPPLY CIRCUIT TERMINAL LOOSENESS AND BATTERY
Check battery terminals for looseness on both positive and negative ones and ground connection. Also make
sure that battery voltage does not drop.
BASIC INSPECTION 2: RAS WARNING LAMP INSPECTION
1. Make sure RAS warning lamp turns on when ignition switch is turned ON.
If it does not turn on, refer to STC-33, "Trouble Diagnosis Chart" .
2. Make sure that RAS warning lamp turns off when the engine is started after ignition switch is turned ON. If
it does not turn off, perform self-diagnosis. Refer to STC-28, "
SELF-DIAG RESULT MODE" .
3. Always erase DTC memory after completing self-diagnosis. Refer to STC-29, "
How to Erase Self-Diag-
nostic Results" .
BASIC INSPECTION 3: RAS CONTROL UNIT POWER SUPPLY CIRCUIT AND GROUND CIR-
CUIT INSPECTION
1. CHECK RAS CONTROL UNIT CONNECTOR
Turn ignition switch OFF, disconnect RAS control unit harness connector, and check terminal for deformation,
disconnection, looseness, etc.
OK or NG
OK >> GO TO 2.
NG >> Poor connection of connector terminal. Repair or replace the terminal.
2. CHECK RAS CONTROL UNIT GROUND CIRCUIT
1. Disconnect RAS control unit harness connector B127, and then
check continuity between RAS control unit harness connector
B127 and ground.
OK or NG
OK >> GO TO 3.
NG >> Ground circuit open or shorted. Repair or replace any
inoperative parts. Terminal 34 – Ground : Continuity
