DTC Confirmation ProcedureINFOID:0000000005928921
NOTE:
If “DTC Confirmation Procedure” has been previously performed, alw ays turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MONI TOR” mode for “TRANSMISSION” with CONSULT-III.
2. Make sure that output voltage of CVT fluid temperature sensor is within the range below.
ATF TEMP SEN: 1.0 - 2.0 V
If out of range, drive the vehicle to decrease the voltage (warm up the fluid) or stop engine to
increase the voltage (cool down the fluid)
3. If DTC is detected, go to CVT-128, "
Diagnosis Procedure" .
Diagnosis ProcedureINFOID:0000000005928922
1.CHECK DTC
1. Turn ignition switch ON. (Do not start engine.)
2. Select “SELF-DIAG RESULTS” mode fo r “TRANSMISSION” with CONSULT-III.
3. Erase self-diagnostic results. Refer to CVT-27, "
OBD-II Diagnostic Trouble Code (DTC)".
4. Turn ignition switch OFF, and wait for 10 seconds or more.
5. Start engine.
6. Confirm self-diagnostic results again. Refer to CVT-48, "
CONSULT-III Function (TRANSMISSION)" .
Is the
“P1745” displayed?
