DTC P1574 ASCD VEHICLE SPEED SENSORPFP:31036
Component DescriptionBBS0053U
The ECM receives two vehicle speed sensor signals via CAN communication line. One is sent from “unified
meter and A/C amp.” and the other is from TCM (Transmission control module). The ECM uses these signals
for ASCD control. Refer to EC-363, "
AUTOMATIC SPEED CONTROL DEVICE (ASCD)" for ASCD functions.

DTC Confirmation ProcedureBBS0053W
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 40 km/h (25 MPH).
4. If DTC is detected, go to EC-612, "
Diagnostic Procedure" .
WITHOUT CONSULT-II
TESTING CONDITION:
Step 2 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.
1. Start engine.
2. Drive the vehicle at more than 40 km/h (25 MPH).
3. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
4. Perform Diagnostic Test Mode II (Self-diagnostic results) with ECM.

PRECAUTIONS

WARNING:
To prevent ECM from storing the diagnostic trouble codes, do not carelessly disconnect the harness
connectors which are related to the engine control system and TCM (transmission control module)
system. The connectors should be disconnected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
Precautions for Three Way CatalystBAS00074
If a large amount of unburned fuel flows into the catalyst, the catalyst temperature will be excessively high. To
prevent this, follow the instructions.

Use unleaded gasoline only. Leaded gasoline will seriously damage the three way catalyst.

When checking for ignition spark or measuring engine compression, make tests quickly and only when
necessary.

Do not run engine when the fuel tank level is low, otherwise the engine may misfire, causing damage to
the catalyst.
Do not place the vehicle on flammable material. Keep flammable material off the exhaust pipe and the three
way catalyst.
Precautions for FuelBAS0008E
QR20DE/VQ23DE ENGINE (REGULAR GASOLINE, UNLEADED PREMIUM GASOLINE RECOM-
MENDED)
Use unleaded regular gasoline with an octane rating of at least 91 RON (research octane number).
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
VQ35DE ENGINE (PREMIUM GASOLINE)
Use unleaded premium gasoline with an octane rating of at least 95 RON (research octane number).
If unleaded premium gasoline is not available, unleaded regular gasoline with an octane rating of at least 91
RON (research octane number) can be used, but only under the following precautions:

have the fuel tank filled only partially with unleaded regular gasoline, and fill up with unleaded premium
gasoline as soon as possible.

avoid full throttle driving and abrupt acceleration.
However, for maximum vehicle performance, the use of unleaded premium gasoline is recommended.
CAUTION:
Do not use leaded gasoline. Using leaded gasoline will damage the three way catalyst. Using a fuel
other than that specified could adversely affect the emission control devices and systems, and could
also affect the warranty coverage validity.
Precautions for Multiport Fuel Injection System or Engine Control SystemBAS0008F

Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to “OFF” position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.

Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.

Be careful not to jar components such as ECM and mass air
flow sensor.
