EXCEPT FOR M/T MODELS : DTC Description

INFOID:0000000010702972

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 

ECM-93, "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.

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.

3.

Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:
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 

ECM-280, "EXCEPT FOR M/T MODELS : Diagnosis Procedure"

.

NO-1

>> To check malfunction symptom before repair: Refer to
