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.

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 B476, and then
check continuity between RAS control unit harness connector
B476 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 should exit.
