Incline the gauge under 90 ° to the right and repeat check. If the result of measurement does not fall outside the limits a range 1.3 ÷ 1.7 In, pass to a following stage of check, otherwise replace the gauge. Check up quality of contact connections and reliability of fixing of sockets. In case of need make corresponding corrections. Restore initial connection of electroconducting. Clear memory of the processor and repeat procedure of reading of diagnostic codes. If any changes (towards improvement) has not occurred, replace assemblage of the module of management VDC. At occurrence of new codes pass to corresponding test. If refusal has not repeated, hence, malfunction carried a temporality, - once again make sure of reliability of fastening of all contact connections. Infringement of serviceability of functioning of the gauge of pressure (DTC 74) The scheme of connection of the gauge of pressure is resulted on an illustration.
Switch off ignition, disunite contact pair F91/VDC5 of the hydromodulator and measure resistance between the plug № 15 sockets F91 and weight of the chassis. If the result of measurement makes less than 0.5 Ohm, following two stages of check can be lowered. Switch off ignition, disconnect electroconducting from the module of management VDC, uncover contact knot of the module, then again connect a socket and measure resistance between the plug № 76 sockets F87 and weight of the chassis. If the result of measurement makes less than 0.5 Ohm, replace electroconducting on a chain site between the module of management and hydromodulator VDC, otherwise pass to a following stage of check. Check up quality of contact connections and reliability of fastening of sockets, in case of need make corresponding corrections, or replace the module of management VDC. Include ignition and measure pressure between plugs № 16 (+) and 15 (-) socket F91. If the result of measurement does not fall outside the limits a range 4.75 ÷ 5.25 In, following two stages of check can be lowered.
Switch off ignition, disconnect electroconducting from the module of management VDC, uncover contact knot of the module (illustrations 41.245а and 41.245b see), then again connect a socket, include ignition and measure pressure between plugs № 78 (+) and № 76 (-) socket F87. If the result of measurement does not fall outside the limits a range 4.75 ÷ 5.25 In, replace electroconducting on a chain site between the module of management and hydromodulator VDC, otherwise pass to a following stage of check. Check up quality of contact connections and reliability of fastening of sockets, in case of need make corresponding corrections, or replace the module of management VDC. Switch off ignition, disconnect electroconducting from the module of management VDC and measure resistance between plugs №№ 13 both 14 sockets F91 and weight of the chassis. If the result of measurement makes more than 1 МОм, pass to a following stage of check, otherwise repair electroconducting on a chain site between the module of management and hydromodulator VDC. Measure pressure between plugs №№ 13 both 14 sockets F91 and weight of the chassis. If the result of measurement makes less than 0.5 In, pass to a following stage of check, otherwise repair electroconducting on a chain site between the module of management and hydromodulator VDC. Include ignition and repeat the check described in the previous paragraph. If the result of measurement makes less than 0.5 In, pass to a following stage of check, otherwise repair electroconducting on a chain site between the module of management and hydromodulator VDC. Switch off ignition, disconnect electroconducting from the module of management VDC, uncover contact knot of the module, then again connect a socket, include ignition and measure pressure between plugs №№ 77 (+) and № 36 (+) and the plug № 76 (-) socket F87. If the result of measurement does not fall outside the limits a range 0.48 ÷ 0.72 In, pass to a following stage of check, otherwise replace hydromodulator VDC. Check up on presence of signs of development of leaks a hydraulic path on a site between ГТЦ and hydromodulator VDC. In case of detection of leaks tighten corresponding sockets, differently pass to a following stage of check. Check up pressure ГТЦ. At positive results of check pass to a following stage of check, otherwise replace ГТЦ. Measure a difference between positions of a pedal of a foot brake in the released position and at squeezing with effort 50 кГс. If the result of measurement makes no more than 95 mm, pass to a following stage of check, otherwise pump over brake system (the Section Prorolling of a hydraulic path of brake system see). Squeeze out a pedal of a foot brake with effort 50 кГс and measure pressure between plugs №№ 77 (+) () and № 36 (+) () and the plug № 76 (-) socket F87. If the difference of results of measurements And and In does not exceed 0.2 In, pass to a following stage of check, otherwise replace hydromodulator VDC. Check up quality of contact connections and reliability of fixing of sockets. In case of need make corresponding corrections. Restore initial connection of electroconducting. Clear memory of the processor and repeat procedure of reading of diagnostic codes. If any changes (towards improvement) has not occurred, replace assemblage of the module of management VDC. At occurrence of new codes pass to corresponding test. If refusal has not repeated, hence, malfunction carried a temporality, - once again make sure of reliability of fastening of all contact connections. Check of signals of input-input of the module of management VDC The scheme of electric connections ABS Card of an arrangement of contact plugs in a socket of the module of management and the scheme of electric connections of components VDC are resulted on illustrations.
