DTC Confirmation ProcedureEBS00K6K
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°C (32 to 86°F)
1. Start engine and warm it up to the 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 one minute under no
load.
4. Let engine idle for one minute.
5. Select “HO2S2 (B1) P0139” of “HO2S2” in “DTC WORK SUPPORT” mode with CONSULT-II.
6. Touch “START”.
7. Let engine idle for at least 30 seconds.
8. 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.
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”.

On Board Diagnosis LogicEBS00KBE
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise. When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction
is indicated.
This self-diagnosis has the one trip detection logic.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to LC-11. Also, replace the
engine oil. Refer to LC-8.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-21.
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckEBS00KBF
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-328,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-328,
"Diagnostic Procedure" .
3. Turn ignition switch “ON”.
