DTC Confirmation ProcedureEBS010O6
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
TESTING CONDITION:

Always perform at a temperature above −10°C (14°F).

Before performing the following procedure, confirm that battery voltage is more than 11V at idle.
WITH CONSULT-II
1. Start engine and warm it up to normal operating temperature.
2. Stop engine and wait at least 10 seconds.
3. Turn ignition switch ON and select “HO2S1 (B1) P0133” of “HO2S1” in “DTC WORK SUPPORT” mode
with CONSULT-II.
4. Touch “START”.
5. Start engine and let it idle for at least 3 minutes.
NOTE:
Never raise engine speed above 3,600 rpm after this step. If
the engine speed limit is exceeded, return to step 5.
6. When the following conditions are met, “TESTING” will be dis-
played on the CONSULT-II screen. Maintain the conditions con-
tinuously until “TESTING” changes to “COMPLETED”. (It will
take approximately 40 to 50 seconds.)
If “TESTING” is not displayed after 5 minutes, retry from step 2.

DTC Confirmation ProcedureEBS010OX
CAUTION:
Always drive vehicle at a safe speed.
NOTE:

“COMPLETED” will appear on CONSULT-II screen when all tests “COND1”, “COND2” and
“COND3” are completed.

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait
at least 10 seconds before conducting the next test.
TESTING CONDITION:
Never stop engine during this procedure. If the engine is stopped, retry this procedure from step 2 in
Procedure for COND1.
WITH CONSULT-II
Procedure for COND1
For the best results, perform DTC WORK SUPPORT at a temperature of 0 to 30°(32 to 86°F).
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Start engine and keep the engine speed between 3,500 and 4,000 rpm for at least 1 minute under no load.
4. Let engine idle 1 minute.
5. Select “HO2S2 (B1) P0139” of “HO2S2” in “DTC WORK SUPPORT” mode with CONSULT-II.
6. Touch “START”.
7. Start engine and let it idle for at least 30 seconds.
8. Rev engine up to 2,000 rpm two or three times quickly under no load.
If “COMPLETED” appears on CONSULT-II screen, go to step 2 in Procedure for COND3.
If “COMPLETED” does not appear on CONSULT-II screen, go to the following step.
9. When the following conditions are met, “TESTING” will be displayed at “COND1” on the CONSULT-II
screen. Maintain the conditions continuously until “TESTING” changes to “COMPLETED”. (It will take
approximately 60 seconds.)
NOTE:

If “TESTING” is not displayed after 5 minutes, retry from step 2 in Procedure for COND1.

If “COMPLETED” already appears at “COND2” on CONSULT-II screen before Procedure for
COND2 is conducted, it is unnecessary to conduct step 1 in Procedure for COND2.

Procedure for COND2
1. While driving, release accelerator pedal completely with “OD”
OFF (A/T) from the above condition [step 9] until “INCOM-
PLETE” at “COND2” on CONSULT-II screen has turned to
“COMPLETED”. (It will take approximately 4 seconds.)
NOTE:
If “COMPLETED” already appears at “COND3” on CONSULT-II
screen before Procedure for COND3 is conducted, it is unnec-
essary to conduct step 1 in Procedure for COND3.
Procedure for COND3
1. Stop vehicle and let it idle until “INCOMPLETE” of “COND3” on
CONSULT-II screen has turned to “COMPLETED”. (It will take a
maximum of approximately 6 minutes.)
2. Make sure that “OK” is displayed after touching “SELF-DIAG
RESULTS”.
If “NG” is displayed, refer to EC-215, "
Diagnostic Procedure" .
If “CAN NOT BE DIAGNOSED” is displayed, perform the follow-
ing.
a. Turn ignition switch OFF and leave the vehicle in a cool place
(soak the vehicle).
b. Turn ignition switch ON and select “COOLAN TEMP/S” in “DATA
MONITOR” mode with CONSULT-II.
c. Start engine and warm it up while monitoring “COOLAN TEMP/S” indication on CONSULT-II.
d. When “COOLAN TEMP/S” indication reaches to 70°(158°F), go to Procedure for COND1 step 3.
Overall Function CheckEBS010OY

6. Check the voltage when revving up to 4,000 rpm under no load
at least 10 times.
(Depress and release accelerator pedal as soon as possible.)
A change of voltage should be more than 0.06V for 1 sec-
ond during this procedure.
If the voltage can be confirmed in step 6, step 7 is not nec-
essary.
7. Keep vehicle at idling for 10 minutes, then check the voltage. Or
check the voltage when coasting from 80 km/h (50 MPH) in D
position with “OD” OFF (A/T), 3rd gear position (M/T).
A change of voltage should be more than 0.06V for 1 sec-
ond during this procedure.

DescriptionEBS010QK
NOTE:
If DTC P0500 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC U1000,
U1001. Refer to EC-133, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
The vehicle speed signal is sent to the combination meter from the “ESP/TCS/ABS control unit” (with ESP
models) or “ABS actuator and electric unit (control unit)” (without ESP models) through CAN communication
line. The combination meter then sends a signal to the ECM through CAN communication line.
