DTC P0501 ASCD VEHICLE SPEED SENSORPFP:24810
Component DescriptionEBS01KHH
The ECM receives vehicle speed sensor signal via CAN communication line. It is sent from combination
meter. The ECM uses this signal for ASCD control. Refer toEC-355, "
AUTOMATIC SPEED CONTROL
DEVICE (ASCD)"for ASCD functions.
On Board Diagnosis LogicEBS01KHI
The MI will not light up for this self-diagnosis.
NOTE:
lIf DTC P0501 is displayed with DTC U1000 first perform the trouble diagnosis for DTC U1000. Refer
toEC-79, "
DTC U1000 CAN COMMUNICATION LINE".
lIf DTC P0501 is displayed with DTC P0606, first perform the trouble diagnosis for DTC P0606.
Refer toEC-215, "
DTC P0606 ECM".
DTC Confirmation ProcedureEBS01KHJ
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
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:
Step 3 may be conducted with the drive wheels lifted in the shop or by driving the vehicle. If a road test
is expected to be easier, it is unnecessary to lift the vehicle.
WITH CONSULT-II
1. Start engine.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Drive the vehicle at more than 10 km/h (6 MPH) for at least 5
seconds.
4. If DTC is detected, go toEC-184, "
Diagnostic Procedure".
