TM 10-3930-675-20-1 0027 00-7 TRANSMISSION SPEED SENSORS TROUBLESHOOTING - CONTINUED 0027 00 Table 7. Error Code 655 - Internal Speed Sensor Failure, Open Circuit or Short Circuit to Battery Troubleshooting Procedures. MALFUNCTION TEST OR INSPECTION CORRECTIVE ACTION Error Code 655 - Internal Speed Sensor Failure, Open Circuit or Short Circuit to Battery 1.  Remove cab transmission and steering ECU panel cover and check transmission ECU connector    for    proper    con- nection (WP 0079 00). Connect  loose  or  disconnected connector. 2.  Remove  cab rear  wall  center panel cover and check connector   X173   for   proper connections. Connect  loose  or  disconnected connectors. 3.  Move cab to transport position and remove transmission access covers (WP 0135 00). 4.  Check transmission electrical harness    connector    752   for proper  connection  at  internal speed sensor. Connect  loose  or  disconnected connectors. 5.  Check     continuity     between connector    752    pin    1    and connector   X173   pin   8   and between connector 752 pin 2 and connector X173 pin 9. a.  If  continuity  is  not  present, repair  or  replace  connectors (WP 0111 00). b.  If   wiring   harness   must   be replaced, notify SRA. 6.  Disconnect    connector    from transmission ECU. 7.  Check     continuity     between transmission  ECU  connector pin 42 and connector X173 pin 8  and  between  transmission ECU   connector   pin   3   and connector X173 pin 5. a.  If  continuity  is  not  present, repair  or  replace  connectors (WP 0111 00). b.  If   wiring   harness   must   be replaced, notify SRA. 8.  Disconnect transmission internal speed sensor connector   752   and   perform internal   resistance   check   of internal speed sensor. Resistance should be 1050 +/- 100 ohms. If resistance is not as specified, replace   internal   speed   sensor (WP 0095 00).
