H. 如果 M17 上没有电压，则转到以下步骤。
（1）打开顶板，取下 PiP 模块。分解步骤参见第 6-4 节。
（2）对于车体接口板上的条形灯 LA 2（夹头打开）和 LA 3（夹头闭合）的位置，请参见图 6-5。接通夹头打开/闭合开关，检查灯是否亮。
（3）如果在操作开关时，应该亮的条形灯亮了，则转到下面的步骤（5）。
（4）如果在操作开关时，有一个条形灯不亮（且只有一个功能有故障），则问题出在开关盒或公文包式控制器组合件中。请联系遥感技术服务部，电话：（865）-483-1492。
（5）对于主继电器板的双色灯（夹头打开/闭合）的位置，请参见图 6-6。接通开关，检查主继电器板上标有“夹头”（GRIP）的双色灯（红/绿）。打开时，双色灯亮，呈红色；闭合时，绿色。
（6）如果主继电器板上应该亮的双色灯亮了，且连接器 M17 的引脚 1 和引脚 2 上没有电压，则问题出在主继电器板与连接器 M17 之间的连线上（例如，插孔胀大了）。必须检查连线的连续性。接头位于悬臂内，肘节延伸与弯头之间，弯头与下悬臂管之下，以及侧翼和车体机架之下。各个连接器的具体引脚输出，见图纸 B-2450-9340 和 D-2450-9910。
（7）如果开关接通时，应该亮的双色灯不亮，而车体接口板上应该亮的条形灯亮，则更换主继电器板。分解步骤参见第 6-4 节。
I. 如果问题仍然存在，请联系遥感技术服务部，电话：（865）-483-1492。
华译网上海翻译公司曾经翻译过大量有关单功能故障的程序资料文件，Beijing Chinese Subtitling Translation Service Agency has translated many technical documents about procedures for single function failures.
H. If no voltage is present on M17 proceed to the following steps:
(1) Open Top Cover and remove PiP Module. Refer to Section 6-4 for disassembly procedures.
(2) Refer to figure 6-5 for location of the Bar LEDs LA 2 (Grip Open) and LA 3 (Grip Close) on the Vehicle Interface Board. Activate the Gripper Open/Close switch and confirm illuminations.
(3) If correct Bar LEDs are illuminating when operating switch, proceed to step (5) below.
(4) If either Bar LED does not illuminate when operating the switch (and there is only a single function failure) the problem is in the Switchbox or Briefcase Assembly. Contact REMOTEC Service Department at (865)-483-1492.
(5) Refer to figure 6-6 for the location of the bi-color LED (Grip Open/Close) on the Main Relay Board. Activate switch and check bi-color LED (RED/GREEN) on the Main Relay Board labeled GRIP. Bi-color LED should illuminate RED for Open and GREEN for Close.
(6) If the correct bi-color LED is illuminating on the Main Relay Board and NO voltage is present on pins 1 & 2 at connector M17, the problem exists in the wiring between the Main Relay Board and connector M17 (e.g., female pins spread apart). The integrity of wiring must be checked. Connections are located inside the arm between the Wrist Pitch Extend and the Elbow , below the Elbow and lower Arm Tube, and below the Shoulder and Vehicle Housing. Specific pin outs for each connector are found on drawings B-2450-9340 and D-2450-9910.
(7) If the correct bi-color LED is not illuminating when activating the switch and the correct Bar LEDs are illuminating on the Vehicle Interface Board, replace the Main Relay Board. Refer to Section 6-4 for disassembly procedures.
I. If the problem still exists, contact REMOTEC Service Department at (865)-483-1492.
