Check of serviceability of functioning of components and problem diagnostics темпостата Primary checksMake sure that target pressure of the onboard storage battery makes not less than 12 In, and electrolit density - not less than 1.260 units. Cable of a drive throttle заслонки Check up correctness of a lining drive a cable темпостата and reliability of its fixing on кулачковом the lever of a drive throttle заслонки, - lever moving should not render any influence on a gas cable. The main switch темпостата Include ignition, translate the switch in position ON (Вкл) and make sure of serviceability of operation of a display lamp of the switch. While translating the switch in position OFF (Выкл) the display lamp should go out. Again include темпостат - the display lamp should light up. Switch off, then again include ignition, - at ignition inclusion the display lamp should remain in the extinguished position (темпостат it is switched off). Trial runs Having left on малозагруженную a direct highway, disperse the car till the speed of 40 km/h (25 miles/ch) and translate the main switch темпостата in position ON (Вкл). By means of the combined operating switch темпостата choose a mode «SET/COAST». Make sure of serviceability поддерживания system of the chosen cruiser high-speed mode. Make sure that the car starts to move with acceleration at отжимании the combined operating switch to position RESUME/ACCEL and comes back to cruiser speed of movement at release the switch. At switch keeping in position SET/COAST the car should start to make braking by the engine with return to the chosen cruiser speed at release the switch.
Make sure of serviceability of switching-off темпостата at squeezing of a pedal of a foot brake, coupling (Manual transmission) and transfer of the operating switch in position CANCEL. Темпостат does not support a cruiser high-speed mode Execute all listed primary checks. If elimination of the revealed malfunctions does not lead to problem elimination, pass to performance of electric checks of signals of input/conclusion, or make reading of diagnostic codes (see more low). Actually supported value of cruiser speed differs from the chosen Check up serviceability of functioning of an actuation mechanism (see more low). If it is not possible to reveal any infringements, replace the management module темпостата (see Has undressed Removal, check of a condition and installation of components of a control system by speed). Check of signals of input/conclusion of the module of management темпостата Tab. 19 Signals of input/conclusion of the module of management темпостата
Reading of codes of malfunctions of a control system by speed
Before to start performance of any works near to the block of a pillow of safety, a steering column or the instrument panel, disconnect SRS in order to avoid reception of traumas at its casual operation (the Section System of additional safety (SRS) - the device and a functioning principle see). Electroconducting of chain SRS is easy for distinguishing on yellow colour of isolation.
Reading is made by means of firm scanner Subaru (SSM). Diagnostics is made in two modes: a mode of refusal and in a mode of real time. For revealing of malfunctions in the first mode carrying out of trial runs is required. The module of self-diagnostics of system will keep codes of the refusals occurring during movement. In case of revealing more than two refusals, corresponding codes will be highlighted by the scanner consistently (as numbering).
During check in a mode of real time check of serviceability of a condition of a subsystem of entrance signals is made. Check is made on the motionless car, simulating signals move on corresponding components темпостата, results are fixed by means of the scanner. Refusal mode темпостата Prepare the scanner, establish a cartridge. Connect SSM to diagnostic socket DLC of the car at the left under the panel of devices. Start the engine and translate the main switch темпостата in position «ON» (Вкл).
In the main menu (Main Menu) choose a mode of the expanded range of checks (All System Diagnosis), - confirm a choice with key pressing «YES».
Disperse the car till the speed not less than 32 km/h (20 miles/ch) at the included mode of installation of cruiser speed темпостата (SET). At spontaneous switching-off темпостата on the scanner display the refusal code will be highlighted, - do not mix the given code with a code corresponding to compulsory switching-off темпостата by the driver (the list of codes of malfunctions in Specifications in the beginning of the Head see). Further pass to checks and the corrections adhered to the highlighted code (see more low). Mode of real time Connect the scanner to diagnostic socket DLC. Include ignition and translate the main switch темпостата in position «ON» (Вкл). In the main menu (Main Menu) choose a mode {Each System Check} and press a key «YES». In the screen menu {System Selection Menu} choose point {Cruise Control}, - confirm a choice with key pressing «YES». Further, be switched in a mode of a conclusion and preservation of the current data (Current Data Display and Save). Make sure of correctness of the data highlighted by the scanner: a) At squeezing of a pedal of a foot brake there should be a switching of positions of the gauge-switch of stoplights (ON/OFF); b) switch SET/COAST Switching should result to switchings of modes of the switch (ON/OFF); c) switch RESUME/ACCEL Switching should result to switchings of modes of the switch (ON/OFF); d) Squeezing of a pedal of coupling should lead to switchings of positions of the gauge-switch of disconnection of a chain of a starter (ON/OFF); e) the Conclusion of the lever of selector AT from position «Р» / »N» should lead to switchings of positions of the gauge-switch of the permission of start (ON/OFF). Clearing of memory of the block of self-diagnostics Memory clearing occurs at ignition deenergizing. Check of serviceability of functioning of components темпостата
