DTC P0503 ASCD VEHICLE SPEED SENSOR
DTC P0503 ASCD VEHICLE SPEED SENSOR
PFP:24810
Component Description
EBS011W9
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-348, "AUTOMATIC SPEED CONTROL
for ASCD functions.
On Board Diagnosis Logic
EBS011WA
This self-diagnosis has the one trip detection logic.
The MI will not light up for this self-diagnosis.
NOTE:
●
If DTC P0503 is displayed with DTC U1000 first perform the trouble diagnosis for DTC U1000. Refer
to
EC-83, "DTC U1000 CAN COMMUNICATION LINE"
.
DTC Confirmation Procedure
EBS011WB
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-223, "Diagnostic Procedure"
.

DTC P0504 ASCD BRAKE SWITCH
DTC P0504 ASCD BRAKE SWITCH
PFP:25320
Component Description
EBS011V9
When the brake pedal is depressed, ASCD brake switch and stop
lamp switch are turned ON. ECM detects the state of the brake pedal
by this input of two kinds (ON/OFF signal).
Refer to
EC-348, "AUTOMATIC SPEED CONTROL DEVICE
for the ASCD function.
CONSULT-II Reference Value in Data Monitor Mode
EBS011VA
Specification data are reference values.
ECM Terminals and Reference Value
EBS011W2
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
