CONFIRMATION DRIVING PATTERN

HINT:

After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for at least 30 seconds.
Turn the ignition switch to ON and wait for 3 seconds or more.
Enter the following menus: Powertrain / Engine / Utility / All Readiness.
Input the DTC: P080512 or P080514.

Check the DTC judgment result.

GTS Display	Description
NORMAL	DTC judgment completed System normal
ABNORMAL	DTC judgment completed System abnormal
INCOMPLETE	DTC judgment not completed Perform driving pattern after confirming DTC enabling conditions
N/A	Unable to perform DTC judgment Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit

HINT:

If the judgment result shows NORMAL, the system is normal.
If the judgment result shows ABNORMAL, the system has a malfunction.
If the judgment result shows INCOMPLETE or N/A, perform the Confirmation Driving Pattern and check the DTC judgment result again.

PROCEDURE

1.	READ VALUE USING GTS (CLUTCH STROKE SENSOR VOLTAGE)

(a) Enter the following menus.

Powertrain > Engine > Data List

Tester Display
Clutch Stroke Sensor Voltage

(b) Read the values displayed on the GTS.

Standard Voltage:

GTS Display	Condition	Specified Condition
CLUTCH STROKE SENSOR VOLTAGE	Clutch pedal fully released	0.5 to 1.1 V
CLUTCH STROKE SENSOR VOLTAGE	Clutch pedal fully depressed	2.6 to 4.5 V

CHECK FOR INTERMITTENT PROBLEMS

2.	CHECK TERMINAL VOLTAGE (POWER SOURCE OF CLUTCH PEDAL STROKE SENSOR ASSEMBLY)

(a) Disconnect the clutch pedal stroke sensor assembly connector.

*a	Front view of wire harness connector (to Clutch Pedal Stroke Sensor Assembly)

(b) Turn the ignition switch to ON.

Standard Voltage:

Tester Connection	Switch Condition	Specified Condition
A107-3 (VDO) - A107-1 (GND)	Ignition switch ON	4.5 to 5.5 V

GO TO STEP 6

3.	CHECK HARNESS AND CONNECTOR (CLUTCH PEDAL STROKE SENSOR ASSEMBLY - ECM)

(a) Disconnect the A106 ECM connector.

(b) Disconnect the A107 clutch pedal stroke sensor assembly connector.

Standard Resistance:

Tester Connection	Condition	Specified Condition
A107-2 (OUT) - A106-52 (CLS)	Always	Below 1 Ω
A106-52 (CLS) - Body ground	Always	10 kΩ or higher

REPAIR OR REPLACE HARNESS OR CONNECTOR

4.	REPLACE CLUTCH PEDAL STROKE SENSOR ASSEMBLY

(a) Replace the clutch pedal stroke sensor assembly.

5.	CHECK WHETHER DTC OUTPUT RECURS (DTC P080512 OR P080514)

(a) Clear the DTCs.

Powertrain > Engine > Clear DTCs

(b) Enter the following menus:

Powertrain > Engine > Trouble Codes

Result	Proceed to
DTC is not output	A
DTC P080512 or P080514 is output	B

END

REPLACE ECM

6.	CHECK HARNESS AND CONNECTOR (CLUTCH PEDAL STROKE SENSOR ASSEMBLY - ECM)

(a) Disconnect the A106 ECM connector.

(b) Disconnect the A107 clutch pedal stroke sensor assembly connector.

Standard Resistance:

Tester Connection	Condition	Specified Condition
A107-1 (GND) - A106-44 (E2CL)	Always	Below 1 Ω
A107-3 (VDO) - A106-43 (VCCL)	Always	Below 1 Ω
A106-44 (E2CL) - Body ground	Always	10 kΩ or higher
A106-43 (VCCL) - Body ground	Always	10 kΩ or higher
