DIAGNOSTIC PROCEDURE
1. CHECK EPS CONTROL UNIT POWER SUPPLY CIRCUIT
1. Turn ignition switch “OFF”.
2. Disconnect EPS control unit harness connector.
3. Turn ignition switch “ON”. (Do not start engine.)
4. Check voltage between EPS control unit harness connector (A)
terminals and ground.
5. Turn ignition switch “OFF”.
6. Check voltage between EPS control unit harness connector (A)
terminals and ground.
7. Connect EPS control unit harness connector.
OK or NG
OK >> GO TO 2.
NG >> Check the following. If any items are damaged, repair or
replace damaged parts.

60 A fusible link (No. m , located in the fuse and fusible link block). Refer to PG-4, "POWER
SUPPLY ROUTING CIRCUIT" .

10 A fuses (No. 2, located in the fuse block). Refer to PG-4, "POWER SUPPLY ROUTING CIR-
CUIT" .

Harness for short or open between battery and EPS control unit harness connector M54 termi-
nal 17.

Harness for short or open between ignition switch and EPS control unit harness connector M53
terminal 10.
2. CHECK EPS CONTROL UNIT GROUND CIRCUIT
1. Turn ignition switch “OFF”.
2. Disconnect EPS control unit harness connector.
3. Check continuity between EPS control unit harness connector
(A) terminal and ground.
Also check harness for short to power.
4. Connect EPS control unit harness connector.
OK or NG
OK >> GO TO 3.
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.

EPS Warning Lamp Does Not Turn OFFUGS0008T
SYMPTOM:
EPS warning lamp does not turn OFF for several seconds after starting the engine.
DIAGNOSTIC PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Perform self-diagnosis. Refer to STC-13, "
SELF-DIAG RESULTS MODE" .
Is any malfunction detected by self-diagnosis?
YES >> Check the malfunctioning system.
NO >> GO TO 2.
2. CHECK EPS CONTROL UNIT POWER SUPPLY CIRCUIT
1. Turn ignition switch “OFF”.
2. Disconnect EPS control unit harness connector.
3. Turn ignition switch “ON”. (Do not start engine.)
4. Check voltage between EPS control unit harness connector (A)
terminals and ground.
5. Turn ignition switch “OFF”.
6. Check voltage between EPS control unit harness connector (A)
terminals and ground.
7. Connect EPS control unit harness connector.
