DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If “DTC CONFIRMATION PROCEDURE” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.
>> GO TO 2.
2.DTC REPRODUCTION PROCEDURE
With CONSULT
1. Turn the ignition switch OFF to ON.
2. Perform “EPS” self-diagnosis.
Is DTC
“C160A” detected?
YES >> Go to STC-19, "Work Flow".
NO >> Inspection End.
DTC Display item Malfunction detected condition Possible cause
C160A HEAT PROTECTION When the steering wheel is operated excessively
and the interior temperature of the power steering
system reaches 118 °C (244.4 °F) or more. (Protec-
tion function)
NOTE:
Although the hydraulic pump electric power steering
system warning lamp turns ON, this is not a system
malfunction. The state returns to normal after stop-
ping steering operation and waiting until the system
interior temperature drops to 90 °C (194 °F) or less. The protection of the hydraulic
pump electric power steering sys-

Diagnosis ProcedureINFOID:0000000009460376
1.PERFORM SELF-DIAGNOSIS
With CONSULT
Perform “EPS” self-diagnosis.
Is a malfunctioning system displayed?
YES >> Check malfunctioning system. Refer to STC-13, "DTC Index".
NO >> GO TO 2.
2.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (1)
With CONSULT
1. Start the engine. CAUTION:
Never drive the vehicle.
2. Turn the steering wheel until it stops.
3. Select “MTR ASSIST” in “DATA MONITOR” of “EPS”.
Is the display value
“100%”?
YES >> GO TO 4.
NO >> GO TO 3.
3.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (2)
With CONSULT
1. Select “C/U TEMP” and “C/U TEMP A” in “DATA MONITOR” of “EPS”.
2. Stop the system until the DATA MONITOR display value drops to “90 °C (194 °F)” or less.
3. Check whether symptom continues.
Did symptom continue?
YES >> GO TO 4.
NO >> This occurs because the protection function lowers the assist force. It is not a system malfunction.
Inspection End.
4.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (3)
With CONSULT
1. Turn the steering wheel to the straight -ahead position. (There is no steering force)
2. Select “BATTERY VOLT” in “DATA MONITOR” of “EPS”.
Is the display value
“10.5 V” or more?
YES >> GO TO 5.
NO >> Check the battery power system. Refer to STC-23, "Diagnosis Procedure"
.
5.CHECK THE POWER STEERING CONTROL MODULE SIGNAL (4)
With CONSULT
Select “ESTM VHCL SPD” in “DATA MONITOR” of “EPS”.
*: This may not agree with the speedometer indication imm ediately after the ignition switch is turned ON. This
is not a malfunction.
Is the check result normal?
YES >> GO TO 6.
NO >> Check the combination meter, ABS actuator and electric unit (control unit). Refer to MWI-18,
"CONSULT Function (METER/M&A)" and BRC-33, "CONSULT Function (ABS)".
Monitor item Test condition Display value
ESTM VHCL SPD When stopped 0.00 km/h or mph
