DTC    P0810    Clutch Position Control Error

для подготовки Нажмите здесь


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 pull rod to pull the release fork, a clutch stroke sensor which detects the pull rod position, and a worm gear which engages the pull rod with the motor.
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.

DTC No.
DTC Detection Condition
Trouble Area
P0810
The TCM detects the following conditions simultaneously:
(1-trip detection logic)
  1. Clutch motor current is 22A or more, or less than -22A for 2 seconds or more
  2. Difference between target clutch position and actual clutch position is 0.3 mm (0.0118 in.) or more
  3. Clutch actuator movement is 122 mm/sec (4.8 in./sec) or less
  1. Clutch actuator assembly (clutch motor)
  2. Clutch mechanical system (clutch cover, clutch disc, release fork, release bearing)
  3. Clutch stroke sensor
  4. TCM

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

INSPECTION PROCEDURE

ПРИМЕЧАНИЕ:
  1. In new clutch actuator assembly installation, perform Clamp Position Adjustment before installing the actuator (See page Нажмите здесь). The pull rods of new clutch actuator assemblies (service supply parts) are not set to the clutch clamp position.
  2. 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 (See page Нажмите здесь). If the sensor or actuator is installed without the initialization and learning, it may cause driving performance degradation or system component breakage.

УКАЗАНИЕ:
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.
  1. Clutch Disc and Clutch Cover
  2. Release Bearing
  3. Clutch Release Fork

1.CHECK OTHER DTC OUTPUT (IN ADDITION TO DTC P0810)

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch on (IG) and turn the tester ON.

  1. Select the following menu items: Powertrain / Multi-Mode M/T / DTC.

  1. Read DTCs.

    If DTC P0810 is detected together with DTC P0806, P0807, P0808 and/or P0900 (DTCs related to the clutch position sensor or clutch actuator motor circuit open/short), troubleshoot those DTCs first.
