DTC P0830: Clutch Pedal Position Switch Circuit Range/Performance <M/T>

CIRCUIT OPERATION

• A battery positive voltage is applied to the clutch pedal position switch output terminal (terminal No. 2) from the ECM (terminal No. 85) via the resistor in the ECM.
  

TECHNICAL DESCRIPTION

• The clutch pedal position switch inputs the high/low voltage into the ECM in accordance with whether the clutch pedal is being pressed.
  
• When the driver presses the clutch pedal while shifting gears, the contact of the clutch pedal position switch closes, causing the low signal to be input into the ECM. At this time, the ECM effects a correction to reduce the fuel injection volume.
  

DTC SET CONDITIONS

• After the engine is started and the vehicle attains a minimum speed of 30 km/h (19 mph), the inversion of the high-low signals of the clutch pedal position switch is not detected even once.
  

FAIL-SAFE AND BACKUP FUNCTION

• None
  

TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:)

• Clutch pedal position switch failed.
  
• Open or shorted clutch pedal position switch circuit, harness damage or connector damage.
  
• ECM failed.
  

	Go to Step 2.

	Repair or replace it. Refer to GROUP 00E, Harness Connector Inspection . Then go to Step 9.

(2)Check for continuity between the clutch pedal position switch side connector terminal No. 1 and No. 2. If the clutch pedal is not pressed, the measurement should indicate the current is not going. If the clutch pedal is pressed, the measurement should indicate the current is going. Q. Are there any abnormalities? Repair it. Then go to Step 9. Go to Step 3.

(2)Turn the ignition switch to the "ON" position. Measure the voltage between terminal No. 2 and ground. Voltage should be battery positive voltage. (3)Turn the ignition switch to the "LOCK" (OFF) position. Q. Is battery positive voltage (approximately 12 volts) present? Go to Step 6. Go to Step 4.

	Go to Step 5.

	Repair or replace it. Refer to GROUP 00E, Harness Connector Inspection . Then go to Step 9.

	Replace the ECM. When the ECM is replaced, register the ID code. Refer to GROUP 42B, ID Code Registration Necessity Judgment Table <Vehicles with KOS> or GROUP 42C, ID Codes Registration Judgment Table <Vehicles with WCM> . Then go to Step 9.

	Repair it. Then go to Step 9.

(2)Check for the continuity between terminal No. 1 and ground. Should be less than 2 ohms. Q. Does continuity exist? Go to Step 7. Repair harness wire between clutch pedal position switch connector C-49 terminal No. 1 and ground because of harness damage. Then go to Step 9.

	Go to Step 8.

	Repair or replace it. Refer to GROUP 00E, Harness Connector Inspection . Then go to Step 9.

	Replace the ECM. When the ECM is replaced, register the ID code. Refer to GROUP 42B, ID Code Registration Necessity Judgment Table <Vehicles with KOS> or GROUP 42C, ID Codes Registration Judgment Table <Vehicles with WCM> . Then go to Step 9.

	Repair it. Then go to Step 9.

caution To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958. (1)Connect scan tool MB991958 to the data link connector. (2)Turn the ignition switch to the "ON" position. (3)Erase the DTC. (4)Drive the vehicle at a minimum speed of 30 km/h (19 mph). (5)After completing the test drive, read the DTC. Turn the ignition switch to the "LOCK" (OFF) position. Q. Is DTC P0830 set? The inspection is complete. Retry the troubleshooting.
