DTC DETECTION LOGIC
To judge malfunctions, the diagnosis checks that the A/F signal computed by ECM from the A/F sensor 1 sig-
nal fluctuates according to fuel feedback control.

SEN1” in “DTC WORK SUPPORT” mode with CONSULT.
2.
Touch “START”.
3.
When the following conditions are met, “TESTING” will be displayed on the CONSULT screen.
DTC No.

NOTE:
Never apply brake when releasing the accelerator pedal.
Which does “TESTING” change to?
COMPLETED>>GO TO 6.
OUT OF CONDITION>>Retry DTC CONFIRMATION PROCEDURE. GO TO 4.
6.
PERFORM DTC CONFIRMATION PROCEDURE FOR MALFUNCTION B-III
Touch “SELF-DIAG RESULT”.
Which is displayed on CONSULT screen?
OK
>> INSPECTION END
NG
>> Proceed to
.
7.
PERFORM COMPONENT FUNCTION CHECK FOR MALFUNCTION B
Perform component function check. Refer to
EC-207, "Component Function Check"
.
NOTE:
Use component function check to check the overall function of the A/F sensor 1 circuit. During this check, a
1st trip DTC might not be confirmed.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Proceed to
.
Component Function Check
INFOID:0000000009651067
1.
PERFORM COMPONENT FUNCTION CHECK
With GST
