MULTI-MODE MANUAL TRANSAXLE SYSTEM, Diagnostic DTC:P0810

DTC Code	DTC Name
P0810	Clutch Position Control Error

DESCRIPTION

In the multi-mode manual transaxle system, the clutch is engaged and disengaged by the TCM using a clutch actuator. The clutch actuator consists of an electric motor which moves the clutch master cylinder, a clutch stroke sensor which detects the clutch master cylinder position, and a worm gear which engages the push rod with the motor.

Clutch Actuator Control Malfunction
DTC No.	DTC Detection Condition	Trouble Area
P0810	The TCM detects the following conditions simultaneously for 2 seconds or more: (1-trip detection logic) Clutch motor current is 30A or more, or less than -30A. Difference between target clutch position and actual clutch position is 0.3 mm (0.0118 in.) or more. Clutch actuator movement is 122 mm/sec (4.8 in./sec) or less.	Clutch actuator assembly (clutch motor) Clutch mechanical system (clutch cover, clutch disc, clutch release with bearing cylinder assembly and hydraulic line) Clutch stroke sensor TCM

Tech Tips

The monitor runs when the vehicle is driven at a vehicle speed of 20 km/h (12.4 mph) or more.

Clutch System Malfunction
DTC No.	DTC Detection Condition	Trouble Area
P0810	All conditions below are detected for 0.5 seconds or more: (1-trip detection logic) Clutch system is normal. Starter is off. Engine speed is 2000 rpm or less. Current and target shift position is N. Vehicle is stopped. Input speed is 400 rpm or more.	Clutch actuator assembly (clutch motor) Clutch mechanical system (clutch cover, clutch disc, clutch release with bearing cylinder assembly and hydraulic line) Clutch stroke sensor TCM

MONITOR DESCRIPTION

Clutch Actuator Control Malfunction
This DTC is set in accordance with the stroke speed of the clutch actuator or the difference between the target clutch position and the actual clutch position. Therefore, if malfunctions occur in the clutch stroke sensor or the clutch motor circuit, the DTCs relating to the sensor or motor circuit open/short (DTC P0806, P0807, P0808, and/or P0900) are set before this DTC is set.

Clutch System Malfunction
With the vehicle stopped and the clutch disengaged, measure the input shaft rotation speed. If the input shaft rotation speed is higher than the standard, DTC P0810 is stored.

CAUTION / NOTICE / HINT

Note

In clutch stroke sensor or clutch actuator assembly replacement, perform Initialization and Learning of the multi-mode manual transaxle system after installing the sensor or actuator Click here. If the sensor or actuator is installed without the initialization and learning, it may cause driving performance degradation or system component breakage.

Tech Tips

If the symptom still occurs even after checking the following parts for dirt, wear, or any defects and replacing the defective parts, replace the TCM.

Clutch disc and clutch cover
Clutch release with bearing cylinder assembly
Hydraulic line
