5) Start the engine.
NOTE:
Make sure the select lever is placed in “P” position
before starting.
6) Using the select lever, turn the “P” position
switch and the “N” position switch to ON.
7) Depress the brake pedal to turn brake switch
ON.
8) Keep the engine speed in 2,500 — 3,000 rpm
range for 40 seconds.
9) Shift the select lever in the “D” range and drive
the vehicle at 5 to 10 km/h (3 to 6 MPH).
NOTE:
•For AWD model, release the parking brake.
•The speed difference between front and rear
wheels may light the ABS warning light, but this in-
dicates no malfunctions. When engine control diag-
nosis is finished, perform the ABS memory
clearance procedure of self-diagnosis system.
10) Using the general scan tool, check DTC and
record the result(s).
NOTE:
•For detailed operation procedure, refer to the
general scan tool operation manual.
•For details concerning DTC, refer to “List of Diag-
nostic Trouble Code (DTC)”.

BD:DTC P0175 SYSTEM TOO RICH (BANK 2)
DTC DETECTING CONDITION:
•Detected when two consecutive driving cycles with fault occur.
•GENERAL DESCRIPTION
TROUBLE SYMPTOM:
•Erroneous idling
•Engine stalls.
•Poor driving performance
CAUTION:
After repair or replacement of faulty parts, perform Clear Memory Mode
Step Check Yes No
