TROUBLESHOOTING\n\nSENSOR CHECK TROUBLE CODE CHART\n\nIf a LED is blinking during the diagnostic sensor check, check the circuit listed for the code in the table below\n(Proceed to the page given for that circuit.)\n\nNo. | Blinking LED | Detecting Condition\n0 | L–AUTO | • Normal\n1 | L–FACE*1 | • Open or short in room temperature sensor circuit.\n2 | L–B/L | • Open or short in ambient temperature sensor circuit.\n3 | L–FOOT | • Open or short in evaporator temperature sensor circuit.\n4 | L–F/D*2 | • Open or short in engine coolant temperature sensor circuit.\n5 | L–DEF*3 | • Open in solar sensor circuit.\n         | • Short in solar sensor circuit.\n6 | L–A/C*4 | • All conditions below are detected for 3 secs. or more.\n              (a) Engine speed 450 rpm or more.\n              (b) Ratio between engine and compressor rpm deviates 20% or more in comparison to normal operation.\n7 | L–FRS | • Open in pressure sensor circuit.\n           | • Abnormal refrigerant pressure    [ below 196 kPa (2.0 kgf/cm2, 28 psi)\n                                                over 3,140 kPa (32.0 kgf/cm2, 455 psi) ]\n8 | L–REC | • Short to ground or power source circuit in air mix damper position sensor circuit.\n9 | L–LO | • Short to ground or power source circuit in air outlet damper position sensor circuit.\n10 | L–M2 | • Air mix damper position sensor value does not change even if A/C amplifier signals the\n             air mix damper control servo motor to operate.\n11 | L–HI | • Air outlet damper position sensor value does not change even if A/C amplifier signals the\n             air outlet damper control servo motor to operate.\n\nHINT:    *1 If the room temp. is approx. –20°C (–4°F) or lower, FACE light may blink even though the\n              system is normal.\n\n         *2 If the ambient temperature is approx. –50°C (–58°F) or lower, the B/L light may blink even\n              though the system is normal.\n\n         *3 If the check is being performed in a dark place, the LED for DEF (solar sensor circuit abnormal)\n              could be blinking.\n\n              In this case, perform diagnostic sensor check again while shining a light, such as an inspection\n              light, on the solar sensor.\n\n              If the light is still blinking, there could be trouble in the solar sensor circuit.","image":"https://tsrm.sasquatchvc.com/images/mk4/AC/AC_020.png","url":"https://tsrm.sasquatchvc.com/mk4/tsrm/AC/20","prev":{"page":19,"url":"https://tsrm.sasquatchvc.com/mk4/tsrm/AC/19","api":"https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/19"},"next":{"page":21,"url":"https://tsrm.sasquatchvc.com/mk4/tsrm/AC/21","api":"https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/21"},"section_url":"https://tsrm.sasquatchvc.com/mk4/tsrm/AC","section_api_pages":["https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/1","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/2","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/3","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/4","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/5","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/6","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/7","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/8","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/9","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/10","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/11","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/12","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/13","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/14","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/15","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/16","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/17","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/18","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/19","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/20","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/21","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/22","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/23","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/24","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/25","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/26","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/27","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/28","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/29","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/30","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/31","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/32","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/33","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/34","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/35","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/36","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/37","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/38","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/39","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/40","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/41","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/42","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/43","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/44","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/45","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/46","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/47","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/48","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/49","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/50","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/51","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/52","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/53","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/54","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/55","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/56","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/57","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/58","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/59","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/60","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/61","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/62","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/63","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/64","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/65","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/66","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/67","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/68","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/69","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/70","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/71","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/72","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/73","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/74","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/75","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/76","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/77","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/78","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/79","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/80","https://tsrm.sasquatchvc.com/api/pages/mk4/tsrm/AC/81","ht
