重慶本田CR-V電信寬帶維修,他行駛時偶爾熄火

一輛行駛里程超20萬km的2009年東風本田C R-V運動型多功能車。(重慶本田CR-V電信寬帶維修)用戶反映:該車在低速行駛過程中偶爾會熄火,但熄火后可以立即再次起動。(重慶本田CR-V電信寬帶維修)

檢查分析:維修人員接車后連接專用診斷儀HDS讀取故障碼,在車輛穩定性控制系統(VSA)內發現含義為“IG1電壓過低”的故障碼。(重慶本田CR-V電信寬帶維修)根據維修手冊的提示,故障原因可能為:發電機輸出電壓異常、熔絲異常、ABS泵電源線異常、ABS泵搭鐵線G202異常、蓄電池及其連接線異常等。(重慶本田CR-V電信寬帶維修)首先檢查儀表臺下熔絲盒內4號7.5 A熔絲正常,沒有虛接的現象。(重慶本田CR-V電信寬帶維修)測量熔絲至ABS泵之間的線路正常。(重慶本田CR-V電信寬帶維修)由于是偶發故障,于是反復晃動線束并進行測量,結果也顯示正常。(重慶本田CR-V電信寬帶維修)檢查并緊固搭鐵點G202,緊固蓄電池連接線。(重慶本田CR-V電信寬帶維修)然后連接診斷儀進行路試,隨時觀察發動機數據流。(重慶本田CR-V電信寬帶維修)

試車過程中,駕駛員在大約40 km/h的速度輕踩了一下剎車,儀表板突然暗了一下,隨即發動機熄火,儀表又恢復正常。(重慶本田CR-V電信寬帶維修)重新起動車輛,發現診斷儀與車輛失去聯系,說明是偶爾電壓過低導致點火能量不足,從而造成發動機熄火。(重慶本田CR-V電信寬帶維修)重點檢查發電機、蓄電池及相關線路,發現蓄電池不是原車型號,本著先易后難的原則,更換了蓄電池,繼續試車,故障一直未出現。(重慶本田CR-V電信寬帶維修)

故障排除:更換蓄電池,并定期進行回訪,故障一直未出現。(重慶本田CR-V電信寬帶維修)

Inspection and analysis: after receiving the vehicle, the maintenance personnel connected the special diagnostic instrument HDS to read the fault code, and found the fault code meaning "Ig1 voltage is too low" in the vehicle stability control system (VSA). (Beihai Honda CR-V car maintenance) according to the prompts in the maintenance manual, the possible causes of the failure are: abnormal output voltage of the generator, abnormal fuse, abnormal power line of ABS pump, abnormal grounding line g202 of ABS pump, abnormal battery and its connecting line, etc. (Beihai Honda CR-V car maintenance) first, check that the fuse box under the dashboard contains No. 4 7.5A fuse, which is normal without virtual connection. (Beihai Honda CR-V vehicle maintenance) the circuit between the measuring fuse and ABS pump is normal. (Beihai Honda CR-V car maintenance) due to occasional fault, the harness was repeatedly wiggled and measured, and the results showed that it was normal. (Beihai Honda CR-V vehicle maintenance) check and tighten the ground point g202 and the battery connecting wire. (Beihai Honda CR-V car maintenance) then connect the diagnostic instrument for road test, and observe the engine data flow at any time. (Beihai Honda CR-V car maintenance)
