①General inspection一般检查
|
|
1. |
Power state is "OFF", disconnect the negative terminal of the 12V battery.电源状态“OFF”，断开蓄电池负极。
|
|
2. |
Check the accelerator pedal harness for damage, breakage, etc.检查加速踏板线束是否存在损坏、断裂等现象。
|
|
3. |
Check the accelerator pedal harness connector for corrosion, damage, etc.检查加速踏板线束接插件是否存在腐蚀、损坏等现象。
|
Are the test results normal?检查结果是否正常？
|
No否 |
Repair or replace accelerator pedal harness or connector.维修或更换加速踏板线束或接插件。 |
|
|
②Check the accelerator pedal 2 depth sensor signal harness检查加速踏板2深度传感器信号线束
|
 |
|
1. |
Power status "ON".电源状态“ON”。
|
|
2. |
Slowly depress the accelerator pedal and use a digital multimeter to measure whether the voltage change between pin 1 of the accelerator pedal harness connector FB53 and ground is normal.缓慢踩下加速踏板，用数字万用表测量加速踏板线束接插件FB53的1号针脚与接地之间的电压变化是否正常。
|
Are the test results normal?检查结果是否正常？
|
No否 |
Repair or replace the accelerator pedal 2 depth sensor signal harness; if the fault persists, go to step 3.维修或更换加速踏板2深度传感器信号线束；若故障依然存在，去步骤3。 |
|
|
③Replace the accelerator pedal更换加速踏板
|
|
1. |
Replace the accelerator pedal with a new one and check whether the fault code and symptoms are eliminated.更换新的加速踏板，检查故障码及症状是否排除。
|
Are the test results normal?检查结果是否正常？
|
Yes是 |
Fault resolved.故障排除。 |
|
|
④Replace vehicle controller更换整车控制器
|
|
1. |
Replace the vehicle controller with a new one and check whether the fault code and symptoms are eliminated.更换新的整车控制器，检查故障码及症状是否排除。
|
Are the test results normal?检查结果是否正常？
|
Yes是 |
Fault resolved.故障排除。 |
|
No否 |
Look for causes from other symptoms.从其他症状查找原因。 |
Caution:注意： |
|
