DTC Confirmation ProcedureEBS00BBZ
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
l"COMPLETED" will appear on CONSULT-II screen when all tests "COND1", "COND2" and
"COND3" are completed.
lIf "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 procedure from step 2 in "Pro-
cedure for COND1"
WITH CONSULT-II
Procedure for COND1
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch "OFF" and wait at least 10 seconds.
3. Turn ignition switch "ON" and select "HO2S2 (B1) P1146" of "HO2S2" in "DTC WORK SUPPORT" mode
with CONSULT-II.
4. Touch "START".
5. Start engine and let it idle for at least 30 seconds.
6. Rev engine up to 2,000 rpm 2 or 3 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.
7. Drive vehicle at a speed of more than 70 km/h (43 MPH) for 2 consecutive minutes.
8. 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:
lIf "TESTING" is not displayed after 5 minutes, retry from step 2 in " Procedure for COND1".
lIf "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".

DTC P1146 HO2S2
Procedure for COND2
1. While driving, release accelerator pedal completed with "OD"
OFF (A/T models only) from the above condition [step 8] until
"INCOMPLETE" at "COND2" on CONSULT-II screen has turned
to "COMPLETED" (It will take approximately 4 seconds.)
NOTE:
If "COMPLETE" already appears at "COND3" on CONSULT-
II screen before "Procedure for COND3" is conducted, it is
unnecessary 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 toEC-300, "
Diagnostic Procedure".
Overall Function CheckEBS00BC0
Use this procedure to check the overall function of the heated oxygen sensor 2 circuit. During this check, a 1st
trip DTC might not be confirmed.
WITH GST
1. Start engine and drive vehicle at a speed of more than 70 km/h (43 MPH) for 2 consecutive minutes.
2. Stop vehicle with engine running.
3. Set voltmeter probes between ECM terminal 95 [HO2S2 (B1) signal] and engine ground.
4. 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.)
The voltage should be below 0.50V at least once during this
procedure.
If the voltage can be confirmed in step 4, step 5 is not nec-
essary.
5. 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).
The voltage should be below 0.50V at least once during this
procedure.
6. If NG, go toEC-300, "
Diagnostic Procedure".

DTC P1212 ESP/TCS/ABS COMMUNICATION LINE
DTC P1212 ESP/TCS/ABS COMMUNICATION LINE
PFP:47850
DescriptionEBS00D0F
NOTE:
If DTC P1212 is displayed with DTC U1000, first perform the trouble diagnosis for DTC U1000. Refer to
EC-114
.
This CAN communication line is used to control the smooth engine operation during ESP/TCS/ABS operation.
Pulse signals are exchanged between ECM and ESP/ABS/TCS control unit.
Be sure to erase the malfunction information such as DTC not only in ESP/TCS/ABS control unit but
also ECM after the ESP/TCS/ABS related repair.
On Board Diagnosis LogicEBS00D0G
Freeze frame data is not stored in the ECM for this self-diagnosis. The MI will not light up for this self-
diagnosis.
DTC Confirmation ProcedureEBS00D0H
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V at idle.
WITH CONSULT-II
1. Turn ignition switch “ON”.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for at least 10 seconds.
4. If a 1st trip DTC is detected, go toEC-310, "
Diagnostic Proce-
dure".
WITH GST
Follow the procedure "WITH CONSULT-II" above.
Diagnostic ProcedureEBS00D2D
