车型丰田大霸王乘用车,装用2TZ-FE型发动机、A46DF型自动变速器。故障现象当把变速杆放在D档位置(接通O/D OFF开关),发动机转速达3 000 r/min以上时,汽车行驶速度仅40～50 km/h。故障检查与排除检查自动变速器油量,发现液面较低。添加自动变速器油至油尺上刻线位置再进行试车,结果仍是如此。把4个车轮顶离地面,检查制动器有无拖滞现象。检查结果制动器无拖滞现象,工作正常。利用自动变速器控制系统中的故障自诊断功能检查自动变速器控制系统中是否存在电路故障。用导线跨接诊断座中的TE1及E2两端子,接通点火开关及
Toyota King King Passenger cars, equipped with 2TZ-FE-type engine, A46DF-type automatic transmission. Fault phenomenon When the gear lever in the D position (connected to the O / D OFF switch), the engine speed of 3 000 r / min or more, the car traveling speed of only 40 ~ 50 km / h. Troubleshooting Check and check the automatic transmission oil, found that the liquid level is low. Add automatic transmission oil to the dipstick on the engraved position and then test run, the result is still the case. Put the top four wheels off the ground and check for brake dragging. Brake test results without delay, working properly. Automatic transmission control system using the fault self-diagnostic function to check the automatic transmission control system for the existence of circuit failure. Connect the two terminals of TE1 and E2 in the diagnostic socket with wires, and turn on the ignition switch
