DESCRIPTION
HINT:
This DTC is applicable to Manual Transaxle models only.
The clutch stroke sensor assembly (for detecting pedal depression amount) and clutch switch assembly (for detecting the pedal depression endpoint) are installed to the clutch pedal. When the engine is stopped by stop and start control, the engine stop and start control ECU receives the clutch pedal depression start signal from the clutch stroke sensor, and starts the engine.
When the engine stop and start control ECU detects the clutch stroke sensor ON signal and clutch switch ON signal are input simultaneously for 1.2 seconds or more, it stores a DTC and flashes the stop and start cancel indicator light.
HINT:
The normal signal conditions are as shown in the table below.
Signal | Clutch Pedal Released | In Transition | Clutch Pedal Depressed |
---|---|---|---|
Clutch pedal stroke sensor | ON | OFF | OFF |
Clutch switch | OFF | OFF | ON |
The ECM receives the ON and OFF signals from the clutch stroke sensor, and sends them to the engine stop and start control ECU using CAN communication.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | Warning Indicate | Memory | Note |
---|---|---|---|---|---|---|
P083011 | Clutch Pedal Switch "A" Circuit Short to Ground | Conditions (a) and (b) are met for 1.2 seconds or more (1 trip detection logic): (a) Ignition switch ON (b) Clutch switch is on when Clutch pedal stroke sensor signal is on. |
| Blinks | DTC stored | SAE Code: P0830 |
CONFIRMATION DRIVING PATTERN
HINT:
DTCs for the stop and start system are not cleared even automatically if the malfunction has been repaired. After repairing the malfunction, be sure to clear the DTCs.

HINT:
In this case, let the vehicle idle to complete the refresh charge. The refresh charge is complete when the Data List item "Status of Battery Charge Control" changes from "Refresh Charge Mode". (Usually, idling the engine for 5 to 60 minutes with the battery temperature at 11°C (51°F) or higher, the refresh charge will be completed.)
If the engine is started with the hood open, the system determines that a jump start has occurred. Therefore, make sure that the hood is closed before starting the engine and driving the vehicle.
CONFIRMATION AFTER TROUBLESHOOTING
(a) Connect the GTS to the DLC3.
(b) Turn the ignition switch to ON and turn the GTS on.
(c) Clear the DTCs.

(d) Start the engine.
(e) Fully depress the clutch pedal for 1 second or more. Release the clutch pedal and wait for at least 1 second.
(f) Repeat the previous step 3 times.
(g) Check that no DTCs are output.

STOP AND START SYSTEM OPERATION CHECK
(a) Start the engine and warm it up.
(b) Turn the air conditioning system off.
(c) Drive the vehicle at 7 km/h (4 mph) or more.
CAUTION:
When performing Confirmation Driving Pattern, obey all speed limits and traffic laws.
(d) Stop the vehicle, move the shift lever to neutral and release the clutch pedal.
(e) Allow the engine to stop by stop and start control.
(f) Depress the clutch pedal and start the engine.

PROCEDURE
1. | READ VALUE USING GTS (CLUTCH LOWER SWITCH) |
Tester Display |
---|
Clutch Lower Switch |
(a) Depress the clutch pedal and read the values displayed on the GTS.
OK:
Tester Display | Condition | Normal Condition |
---|---|---|
Clutch Lower Switch | Fully Depressed | ON |
Clutch Lower Switch | Fully Released | OFF |
OK |
![]() | USE SIMULATION METHOD TO CHECK |

|
3. | CHECK HARNESS AND CONNECTOR (ENGINE STOP AND START ECU - CLUTCH START SWITCH ASSEMBLY) |
(a) Disconnect the A67 engine stop and start ECU connector.
(b) Disconnect the A64 clutch start switch assembly connector.
(c) Disconnect the H45 certification ECU (smart key ECU assembly) connector.
(d) Disconnect the A106 ECM connector.
(e) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
A67-17 (CLL) - A64-1 (L) | Always | Below 1 Ω |
A67-17 (CLL) - Body ground | Always | 10 kΩ or higher |
A64-1 (L) - Body ground | Always | 10 kΩ or higher |
OK |
![]() | REPLACE ENGINE STOP AND START ECU |

![]() | REPAIR OR REPLACE HARNESS OR CONNECTOR |
WARNING
When removing the fuel-filler cap, loosen the cap slightly and wait for any hissing to stop, then remove it
Fuel spray is dangerous. Fuel can burn skin and eyes and cause illness if ingested. Fuel spray is released when there is pressure in the fuel tank and the fuel-filler cap is removed too quickly.
