Repair and operation of the car

Check of serviceability of functioning of components and problem diagnostics of a tempostat

Primary checks

Make sure that the output tension of the onboard battery makes not less than 12 V, and electrolyte density - not less than 1.260 units.

Cable of the drive of a butterfly valve

Check correctness of laying of a driving cable of a tempostat and reliability of its fixing on the cam lever of the drive of a butterfly valve, - movement of the lever should not have any impact on a gas cable.

Estimate the size of a free wheeling of a driving cable, - the longitudinal side play on a cam should not exceed 1 mm. In case of need make the corresponding adjustment by rotation of an adjusting nut. Having finished adjustment track reliability of fixing in a reception flute of a protective cover.

Main switch of a tempostat

Include ignition, transfer the switch to the situation ON (Vkl) and make sure of serviceability of operation of an indicator lamp of the switch. At transfer of the switch to the situation OFF (Vykl) the indicator lamp has to go out.

Again include tempostat - the indicator lamp has to light up. Switch off, then again include ignition, - at ignition inclusion the indicator lamp has to remain in the extinguished situation (tempostat it is switched off).

Trial runs

Having come out to the low-loaded direct highway, accelerate the car to the speed of 40 km/h (25 miles/h) and transfer the main switch of a tempostat to the situation ON (Vkl). By means of the combined operating switch of a tempostat choose the SET/COAST mode. Make sure of serviceability of support by system of the chosen cruiser high-speed mode.

Make sure that the car starts moving with acceleration at push-up of the combined operating switch to the situation RESUME/ACCEL and comes back to the cruiser speed of the movement at a switch otpuskaniye.

When keeping the switch in the situation SET/COAST the car has to start making braking by the engine with return to the chosen cruiser speed at a switch otpuskaniye.

At reduction in the rate of the movement of the car lower than 32 km/h (20 miles/h) tempostat it has to be disconnected automatically.

Reading of codes of malfunctions of a control system of speed

The models of cars considered in the present manual are equipped with system of additional safety (SRS).

Before starting performance of any works near the block of a safety cushion, a steering column or the dashboard, disconnect SRS in order to avoid receiving injuries at its casual operation (see the Section System of Additional Safety (SRS) - the device and the principle of functioning). It is easy to distinguish an electrical wiring of a chain of SRS on yellow color of isolation.

Make connection of the SSM scanner strictly according to instructions of manufacturers of the device!

During check the help of the assistant is required.

Reading is made by means of the firm Subaru (SSM) scanner. Diagnostics is made in two modes: mode of refusal and in real time.

Detection of malfunctions in the first mode requires carrying out trial runs. The module of self-diagnostics of system will keep codes of the refusals happening during the movement. In case of identification more than two refusals, the corresponding codes will be highlighted by the scanner consistently (as numbering).

In the mode of refusals the module of management will fix not only the emergency, but also regular shutdowns of a tempostat made at the command of the driver.

Transfer of the main switch to the situation "OFF", as well as switching off of ignition will be led to cleaning of memory of the processor of the DTC codes brought in it during check!

During check check of serviceability of a condition of a subsystem of entrance signals is in real time made. Check is made on the motionless car, the imitating signals are given on the corresponding components of a tempostat, results are fixed by means of the scanner.

the tyvaniye of codes of malfunctions can be made also in the mode {Cruise Control Diagnosis} by a reference choice { Cancel Code (s) of Display }

Accelerate the car to the speed not less than 32 km/h (20 miles/h) at the included mode of installation of cruiser speed of a tempostat (SET). At spontaneous shutdown of a tempostat on the display of the scanner the refusal code will be highlighted, - do not mix this code with the code corresponding to compulsory shutdown of a tempostat by the driver (see the list of codes of malfunctions in Specifications at the beginning of the Head).

Further pass to the checks and corrections attached to the highlighted code (see below).

Mode of real time

Connect the scanner to the diagnostic DLC socket. Include ignition and transfer the main switch of a tempostat to the situation "ON" (Vkl).

In the main menu (Main Menu) choose the mode {Each System Check} and press the YES key.

In the screen menu {System Selection Menu} select item {Cruise Control}, - confirm a choice with pressing of the YES key.

Further, switch in the mode of a conclusion and saving of the current data (Current Data Display & Save).

Make sure of correctness of the data highlighted by the scanner:

a) When squeezing a pedal of a foot brake there has to be a switching of provisions of the sensor switch of stoplights (ON/OFF);
b) Switching of the SET/COAST switch has to bring to switchings of the modes of the switch (ON/OFF);
c) Switching of the RESUME/ACCEL switch has to bring to switchings of the modes of the switch (ON/OFF);
d) Squeezing of a pedal of coupling has to lead to switchings of provisions of the sensor switch of disconnection of a chain of a starter (ON/OFF);
e) The AT selector lever conclusion from situation "P" / has to lead" N" to switchings of provisions of the sensor switch of permission of start (ON/OFF).

Cleaning of memory of the block of self-diagnostics

Cleaning of memory happens at ignition switching off.
