{"model":"mk3","model_name":"MK3 Supra","vehicle":"Toyota Supra A70 (1986.5–1992, 7M-GE / 7M-GTE)","document":"Repair Manual","section":"FI","section_name":"EFI System","page":6,"pages_in_section":126,"title":"EFI System","section_header":"EFI System — Inspection Precautions","ocr_text":"IF VEHICLE IS EQUIPPED WITH MOBILE RADIO SYSTEM (HAM, CB, ETC)\n\nThe ECU has been designed so that it will not be affected by outside interference.\n\nHowever, if your vehicle is equipped with a CB radio transceiver, etc. (even one with about 10 W output), it may, at times, have an affect upon ECU operation, especially if the antenna and feeder are installed nearby.\n\nTherefore, observe the following precautions:\n\n1. Install the antenna as far as possible from the ECU. The ECU is located behind the glove box, so the antenna should be installed in the rear of the vehicle.\n\n2. Keep the antenna feeder as far away as possible from the ECU wires at least 20 cm (7.87 in.) and especially do not wind them together.\n\n3. Check that the feeder and antenna are properly adjusted.\n\n4. Do not equip your vehicle with a powerful mobile radio system.\n\n5. Do not open the cover or the case of the ECU unless absolutely necessary. (If the IC terminals are touched, the IC may be destroyed by static electricity.)\n\nAIR INDUCTION SYSTEM\n\n1. Separation the engine dipstick, oil filler cap, PCV hose, etc., may cause the engine to run out of tune.\n\n2. Disconnection, looseness or cracks in the parts of the air intake system between the air flow meter and cylinder head will allow air suction and cause the engine to run out of tune.","image":"https://tsrm.sasquatchvc.com/images/mk3/FI/FI_006.png","url":"https://tsrm.sasquatchvc.com/mk3/tsrm/FI/6","prev":{"page":5,"url":"https://tsrm.sasquatchvc.com/mk3/tsrm/FI/5","api":"https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/5"},"next":{"page":7,"url":"https://tsrm.sasquatchvc.com/mk3/tsrm/FI/7","api":"https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/7"},"section_url":"https://tsrm.sasquatchvc.com/mk3/tsrm/FI","section_api_pages":["https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/1","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/2","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/3","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/4","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/5","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/6","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/7","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/8","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/9","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/10","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/11","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/12","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/13","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/14","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/15","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/16","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/17","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/18","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/19","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/20","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/21","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/22","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/23","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/24","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/25","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/26","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/27","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/28","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/29","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/30","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/31","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/32","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/33","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/34","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/35","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/36","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/37","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/38","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/39","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/40","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/41","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/42","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/43","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/44","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/45","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/46","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/47","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/48","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/49","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/50","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/51","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/52","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/53","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/54","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/55","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/56","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/57","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/58","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/59","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/60","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/61","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/62","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/63","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/64","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/65","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/66","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/67","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/68","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/69","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/70","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/71","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/72","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/73","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/74","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/75","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/76","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/77","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/78","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/79","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/80","https://tsrm.sasquatchvc.com/api/pages/mk3/tsrm/FI/81","https://tsrm
