INSPECT ACTUATOR RESISTANCE\nMeasure the resistance value between terminals as follows.\nResistance: 3 — 2 approx. 30 Ω\n            1 — 3 approx. 65 Ω\nIf the resistance value is not as specified, replace the actuator.\n\n2. INSPECT ACTUATOR OPERATION\n(a) Connect the positive (+) lead from battery to terminals 2 and 1, and the negative (—) lead to terminal 3.\n(b) Slowly apply vacuum from 0 — 300 mmHg (0 — 11.81 in.Hg, 0 — 40.0 kPa), and check that the control cable can be pulled smoothly.\n\n(c) Disconnect terminal 2 or 1 and check that the control cable returns to its original position and the vacuum returns to 0 mmHg (0 in.Hg, 0 kPa).\n\nIf operation is not as specified, replace the actuator.\n\n3. INSPECT CONTROL CABLE FREEPLAY\n(a) Connect the positive (+) lead from battery to terminals 2 and 3, and 1 the negative (—) lead to terminal 1.\n(b) Slowly apply vacuum from 0 — 300 mmHg (0 — 11.81 in.Hg, 0 — 40.0 kPa), and measure the cable stroke to where the throttle valve begins to open.\nStandard: Approx. within 10 mm (0.39 in.) with a slight amount of freeplay.\nIf freeplay is not as specified, adjust the control cable freeplay.","image":"https://tsrm.sasquatchvc.com/images/mk3/BE/BE_083.png","url":"https://tsrm.sasquatchvc.com/mk3/tsrm/BE/83","prev":{"page":82,"url":"https://tsrm.sasquatchvc.com/mk3/tsrm/BE/82","api":"https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/82"},"next":{"page":84,"url":"https://tsrm.sasquatchvc.com/mk3/tsrm/BE/84","api":"https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/84"},"section_url":"https://tsrm.sasquatchvc.com/mk3/tsrm/BE","section_api_pages":["https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/1","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/2","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/3","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/4","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/5","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/6","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/7","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/8","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/9","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/10","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/11","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/12","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/13","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/14","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/15","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/16","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/17","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/18","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/19","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/20","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/21","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/22","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/23","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/24","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/25","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/26","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/27","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/28","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/29","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/30","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/31","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/32","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/33","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/34","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/35","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/36","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/37","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/38","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/39","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/40","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/41","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/42","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/43","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/44","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/45","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/46","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/47","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/48","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/49","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/50","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/51","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/52","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/53","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/54","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/55","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/56","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/57","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/58","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/59","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/60","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/61","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/62","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/63","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/64","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/65","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/66","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/67","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/68","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/69","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/70","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/71","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/72","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/73","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/74","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/75","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/76","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/77","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/78","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/79","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/80","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/BE/81","h
