P0500 VSS

DTC Description

INFOID:0000000010775191

ECM receives vehicle speed signals from two different paths via CAN communication line: One is from the
ABS actuator and electric unit (control unit) via the combination unit and the other is from TCM.

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Combination meter
• ABS actuator and electric unit (control unit)
• Wheel sensor
• TCM
• Output speed sensor

FAIL-SAFE

DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P0500 is displayed with DTC UXXXX or P0607, first perform the trouble diagnosis for DTC UXXXX or
P0607.

Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to

EC-109, "DTC Index"

.

NO

>> GO TO 2.

2.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting 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.

TESTING CONDITION:

DTC No.

VEHICLE SPEED SENSOR A
(Vehicle speed sensor “A”

At 20 km/h (13 MPH), ECM detects the following status continuously for 5
seconds or more: The difference between a vehicle speed calculated by a
output speed sensor transmitted from TCM to ECM via CAN communica-
tion and the vehicle speed indicated on the combination meter exceeds
15km/h (10 MPH).

Engine operating condition in fail-safe mode

Fail safe mode

Vehicle behavior

Traveling con-
trol mode

Accelerator an-
gle variation
control

ECM controls the accelerator pedal depression speed to make it slower than actual speed. This
causes a drop in accelerating performance and encourages the driver to repair malfunction.
NOTE:
ECM does not control the accelerator pedal releasing speed.

Combustion
control mode

Stratified charge
combustion
control at start-
ing

No stratified charge combustion at starting (cold start).

Idle speed con-
trol

Stops feedback control of idle speed and controls with specified speed.

Recovery speed
control at decel-
erating

Stops recovery speed control by the fuel cut at decelerating and controls with specified speed.

Idle neutral con-
trol

Stops idle neutral control.

Before performing the following procedure, confirm that battery voltage is 10 V or more at idle.

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Start engine.

2.

Shift the selector lever to D range and wait at least for 2 seconds.

3.

Drive the vehicle at least 5 seconds at 20 km/h (13 MPH) or more.

CAUTION:

Always drive vehicle at a safe speed.
NOTE:
This procedure 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.

4.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Proceed to

EC-299, "Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to

GI-44, "Intermittent Incident"

P0506 ISC SYSTEM

P0506 ISC SYSTEM

DTC Description

INFOID:0000000010775193

The ECM controls the engine idle speed to a specified level through the fine adjustment of the air, which is let
into the intake manifold, by operating the electric throttle control actuator. The operating of the throttle valve is
varied to allow for optimum control of the engine idling speed. The crankshaft position sensor (POS) detects
the actual engine speed and sends a signal to the ECM.
The ECM controls the electric throttle control actuator so that the engine speed coincides with the target value
memorized in the ECM. The target engine speed is the lowest speed at which the engine can operate steadily.
The optimum value stored in the ECM is determined by taking into consideration various engine conditions,
such as during warming up, deceleration and engine load (air conditioner, power steering and cooling fan
operation, etc.).

DTC DETECTION LOGIC

POSSIBLE CAUSE

• Electric throttle control actuator
• Intake air leaks

FAIL-SAFE

DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P0506 is displayed with other DTC, first perform the trouble diagnosis for other DTC.

Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to

EC-109, "DTC Index"

.

NO

>> GO TO 2.

2.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test. When the target idle speed is not the specified value, perform

EC-426,

"Inspection"

before conducting DTC Confirmation Procedure.

TESTING CONDITION:
• Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.
• Always perform at a temperature above

−

10

°

C (14

°

F).

NOTE:
In the highlands of over 2,400m altitude, DTC may be detected without abnormality, but that case is not abnor-
mal if the DTC is not detected when "DTC confirmation procedure" is performed at under 2,400m altitude.
