P1574 ASCD VEHICL
E SPEED SENSOR
P1574 ASCD VEHICLE SPEED SENSOR
DescriptionINFOID:0000000009462782
The ECM receives two vehicle speed signals via CAN communication line. One is sent from combination
meter, and the other is from TCM (Transmission contro l module). The ECM uses these signals for ASCD con-
trol. Refer to EC-574, "AUTOMATIC SPEED CONTROL DE VICE (ASCD) : System Description"
for ASCD
functions.
DTC LogicINFOID:0000000009462783
DTC DETECTION LOGIC
NOTE:
• If DTC P1574 is displayed with DTC UXXXX, first perform the tr ouble diagnosis for DTC UXXXX.
• If DTC P1574 is displayed with DTC P0500, first pe rform the trouble diagnosis for DTC P0500. Refer
to EC-867, "DTC Logic"
.
• If DTC P1574 is displayed with DTC P0605, first pe rform the trouble diagnosis for DTC P0605. Refer
to EC-883, "DTC Logic"
.
• If DTC P1574 is displayed with DTC P0607, first pe rform the trouble diagnosis for DTC P0607. Refer
to EC-884, "DTC Logic"
.
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conduct-
ing the next test.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Start engine (VDC switch OFF).
2. Drive the vehicle at more than 40 km/h (25 MPH). CAUTION:
Always drive vehicle at a safe speed.
NOTE:
This procedure may be conducted with the drive wheel s 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.
3. Check DTC.
Is DTC detected?
YES >> Proceed to EC-918, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000009462784

27. Remove the LH and RH drive shafts. Refer to
FAX-10, "Removal and Installation (LH)", FAX-12, "Removal
and Installation (RH)".
28. Remove the drive belt. Refer to EM-19, "Removal and Installation"
.
29. Remove the front suspension member. Refer to FSU-20, "Removal and Installation"
.
30. Remove the A/C compressor with piping connected and support using suitable wire.
31. Disconnect the transaxle shift controls. Refer to TM-407, "Removal and Installation"
.
32. Install engine slingers into the rear of the cylinder head (A) and front engine mounting bracket holes (B).
• Use engine mounting bolt holes for front slinger.
• Use the holes in the rear of the cylinder head for the rear
slinger.
33. Support engine and transaxle assembly with engine lifti ng equipment from the top with the vehicle raised
on a hoist.
34. Remove the RH engine mount torque rod, RH engine support bracket and RH engine mounting insulator and bracket.
35. Remove LH transaxle mounting insulator through-bolts.
36. Lower the engine and transaxle assembly from the engine compartment using suitable tool.
CAUTION:
• Before and during this procedure, alw ays check if any harnesses are left connected.
• Avoid any damage to, or any oil/grease smearing or spills onto the engine mounting insulators.
37. Remove the starter motor. Refer to STR-22, "QR25DE : Removal and Installation"

INSTALLATION
Installation is in the reverse order of removal.
NOTE:
Tighten the transmission bolts to specification. Refer to TM-407, "Removal and Installation"
.
• Do not allow oil to get on mounting insulators. Be careful not to damage mounting insulators.
• If parts have a direction mark (arrow) this indicates front of the vehicle, and the parts must be installed
according to the identification mark.
• Install the RH engine mounting bracket bolts in the following steps:
- First install bolts (A) and (B) loosely.
- Install and tighten the five RH engine mounting bracket bolts to specification in the order as shown.
- : Front
INSPECTION AFTER INSTALLATION
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "FOR USA AND CANADA : Fluids and Lubricants"
.
• Use procedure below to check for fuel leakage.
• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak- age at connection points.
• Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration. Slinger bolts (A) : 28 N·m (2.8 kg-m, 21 ft-lb)
Slinger bolts (B) : 48 N·m (4.9 kg-m, 35 ft-lb))

NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
• Bleed air from passages in lines and hoses, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to spec- ified level, if necessary.
