ELECTRONIC CONTROL DEVICE (ECU)
Removal
| PERFORMANCE ORDER |
| 1. The electronic control device of system cruise control is located in the lower part of the dashboard from the driver. |
| 2. Remove the proof-reader of light of headlights. |
| 3. Remove a weight wire from the accumulator. |
| 4. Remove a steering wheel. |
| 5. Remove from the dashboard the left and right loudspeakers. |
| 6. Remove the proof-reader of light of headlights. |
| 7. Remove clamps and remove a covering located round pedals. |
| 8. Disconnect electric sockets, unscrew screws and remove the block of the electronic control device. |
|
Installation
| PERFORMANCE ORDER |
| 1. Installation is made in sequence, return to removal. |

EXECUTIVE MECHANISM OF SYSTEM CRUISE CONTROL
Removal
| PERFORMANCE ORDER |
| 1. The executive mechanism of system cruise control is established sideways the block of cylinders. |
| 2. On the majority of models for access to the executive mechanism it is necessary to remove a casing of the air filter. For further improvement of access to the executive mechanism tighten the parking brake, lift a forward part of the car and fix on supports. Unscrew screws and remove an engine mudguard. |
| 3. Remove a weight wire from the accumulator. Disconnect the electric socket of the executive mechanism located on a plait of wires. |
| 4. Using a screw-driver edge, remove draft from the spherical hinge of the executive mechanism. |
| 5. Unscrew the nuts, fixing an arm of the executive mechanism to the block of cylinders and remove the executive mechanism together with an arm. |
| 6. If necessary unscrew bolts and remove the executive mechanism from an arm. Thus note an arrangement of rubber pillows and laying. |
|
Installation
| PERFORMANCE ORDER |
| 1. Installation is made in sequence, return to removal. At installation of the executive mechanism check a condition of rubber pillows. If necessary the length of draft can be adjusted, for what it is necessary to weaken a lock-nut and to screw or screw together spherical sharnirny connection from draft. After adjustment of length of draft tighten a lock-nut. |
