SYSTEM\n\nINSPECTION PROCEDURE\n\n1 Check voltage between terminals VR2 and VR3 of ECU connector.\n\nON\nDecelation Side\nAccelation Side\nControl Plate\nVR3\nVR2\nBE3840 N08713\nN08757\n\nP Remove ECU with connectors still connected.\n\nC (1) Turn ignition switch ON.\n(2) Measure voltage between terminals VR2 and VR3 of ECU connector while turning control plate slowly by hand from the deceleration side to the acceleration side.\n\nOK Voltage:\nFully closed: approx. 1.3 V\nFully opened: approx. 4.1 V\nIn addition, as the control plate is turned, the voltage should increase gradually without interruption.\n\nNG\n\nOK Proceed to next circuit inspection shown on matrix chart (See page BE–170).\n\n2 Check actuator position sensor.\n\n2\n1\n3\n\nDecelation Side\nAccelation Side\nControl Plate\nBE3945\nN08713\n\nP (1) Remove cruise control actuator.\n(2) Disconnect the actuator connector.\n\nC Measure resistance between actuator terminals 1 and 3 of actuator connector.\n\nOK Resistance: Approx. 2.2 k Ω\n\nC Measure resistance between actuator terminals 2 and 3 of actuator connector, while turning the control plate slowly by hand from the deceleration side to the acceleration side.\n\nOK Resistance:\nFully closed: Approx. 260 k Ω\nFully opened: Approx. 2.2 k Ω\nIn addition, as the control plate turns, the resistance should increase gradually without interruption.\n\nOK\n\nNG Replace actuator assembly.\n\n3 Check for open and short in harness and connector between ECU and actuator position sensor (See page IN–30).\n\nOK\n\nNG Repair or replace harness or connector.\n\nCheck harness and connector for loose connection.\nIf connection is normal check and replace ECU.","image":"https://tsrm.sasquatchvc.com/images/mk4/BE/BE_176.png","url":"https://tsrm.sasquatchvc.com/mk4/tsrm/BE/176","prev":{"page":175,"url":"https://tsrm.sasquatchvc.com/mk4/tsrm/BE/175","api":"https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/175"},"next":{"page":177,"url":"https://tsrm.sasquatchvc.com/mk4/tsrm/BE/177","api":"https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/177"},"section_url":"https://tsrm.sasquatchvc.com/mk4/tsrm/BE","section_api_pages":["https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/1","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/2","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/3","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/4","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/5","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/6","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/7","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/8","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/9","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/10","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/11","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/12","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/13","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/14","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/15","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/16","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/17","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/18","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/19","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/20","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/21","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/22","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/23","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/24","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/25","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/26","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/27","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/28","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/29","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/30","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/31","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/32","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/33","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/34","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/35","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/36","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/37","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/38","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/39","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/40","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/41","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/42","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/43","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/44","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/45","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/46","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/47","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/48","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/49","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/50","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/51","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/52","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/53","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/54","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/55","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/56","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/57","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/58","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/59","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/60","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/61","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/62","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/63","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/64","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/65","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/66","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/67","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/68","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/69","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/70","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/71","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/72","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/73","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/74","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/75","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/76","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/77","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/78","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/79","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/80","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/BE/81",
