| температура охлаждающей жидкости выше 80 ° C vehicle being driven with alternating full-load acceleration and foot off | check the vacuum pipes: - matching of the coloured marks - conformity of the connections - clamping and routes (pipes kinked, pierced) take the readings as indicated below, then refer to the checks described at A, B, C or D depending on the results obtained температура охлаждающей жидкости выше 80 ° C, автомобиль неподвижен: - определите значение измеренного расхода воздуха (AIR FLOW MEAS.) при 2000 об/мин и 3000 об/мин A/ if at 2000 rpm, the air flow measured is greater than 23 g/s, check: - the throttle spindle rotates freely - the return of the throttle to the open position - the engine air supply circuit (condition of the air filter, sleeves) - the operation of the throttle control solenoid valve (тест исполнительных элементов) B/ if at 2000 rpm, the air flow measured is greater than 37 g/s, check: - the operation of the exhaust gas recirculation solenoid valve (EGR VALVE fault, тест исполнительных элементов) - the operation of the throttle control solenoid valve (тест исполнительных элементов) - the operation of the exhaust gas recirculation valve - check the vacuum source (vacuum pump, brake servo unit) C/ if at 3000 rpm, the air flow measured is less than 53 g/s, check: - the operation of the exhaust gas recirculation valve (EGR VALVE fault, тест исполнительных элементов) D/ if at 3000 rpm, the air flow measured is greater than 67 g/s, check зажигание включено: - presence of 12 V at terminal 3 on 1310 при работающем двигателе: 0,5V ≤ U ≤ 5V between terminal 5 of the 4V NR connector and earth, depending on the engine load зажигание включено: - R ≤ 1Ω between terminal 1 of the flow meter 1310 and earth R ≤ 1Ω between terminal 2 and terminal 52 of ECU 1325 check continuity of wires: M, M13, 48A check the continuity and insulation of the wires: 48A, 131, M52, 531 |
