DTC P0501 ASCD VEHICLE SPEED SENSOR

DTC P0501 ASCD VEHICLE SPEED SENSORPFP:24810
Component DescriptionEBS01FAZ
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 to EC-1339, "
AUTOMATIC SPEED CONTROL
DEVICE (ASCD)" for ASCD functions.
On Board Diagnosis LogicEBS01FB0
This self-diagnosis has the one trip detection logic.
The MI will not light up for this self-diagnosis.
NOTE:

If DTC P0501 is displayed with DTC U1000 first perform the trouble diagnosis for DTC U1000. Refer
to EC-1056, "
DTC U1000 CAN COMMUNICATION LINE" .
DTC Confirmation ProcedureEBS01FB1
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 (ESP switch OFF).
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 to EC-1201, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II” above.

Diagnostic ProcedureEBS01FB2
1. CHECK DTC WITH ESP/TCS/ABS CONTROL UNIT (MODELS WITH ESP) OR ABS ACTUATOR AND
ELECTRIC UNIT (CONTROL UNIT) (MODELS WITHOUT ESP)
Refer to BRC-60, "
TROUBLE DIAGNOSIS" (models with ESP) or BRC-12, "TROUBLE DIAGNOSIS" (mod-
els without ESP).
OK or NG
OK >> GO TO 2.
NG >> Repair or replace.
2. CHECK COMBINATION METER
Check combination meter function.
Refer to DI-4, "

DTC Confirmation ProcedureEBS01FC3
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 and warm it up to normal operating temperature (ESP switch OFF).
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Maintain the following condition for at least 5 seconds.
4. If DTC is detected, go to EC-1203, "
Diagnostic Procedure" .
WITH GST
Follow the procedure “WITH CONSULT-II” above.
