FLA -210 FUEL SYSTEM TERMINAL AND CONNECTOR INSPECTION E570B72D Refer to DTC P0110. SIGNAL CIRCUIT INSPECTION E1D80CD4 1. Check voltage 1) IG "OFF" and disconnect IATS connector. 2) IG "ON" and ENG "OFF" 3) Measure voltage between terminal 4 of IATS harness connector and chassis ground. Specification : Approx. 5V 4) Is the measured voltage within specification ? YES ▶ Go to "Ground Circuit Inspection" procedure. NO ▶ If the voltage is 0V, go to "Check open in harness" as follows. If the voltage is more than 5.1V, go to "Check 2. Check short to battery in harness 1) IG "OFF" and disconnect IATS connector and PCM connector. 2) Measure resistance between terminals 2 and 4 of IATS harness connector. 3) Measure resistance between terminals 1 and 4 of IATS harness connector. Specification : Infinite 4) Is the measured resistance within specification? YES ▶ Go to "Component Inspection" procedure. NO ▶ Repair short to battery in harness and go to "Verification of Vehicle Repair" procedure. 3. Check open in harness 1) IG "OFF" and disconnect IATS connector and PCM connctor. 2) Measure resistance between terminal 4 of IATS harness connector and C30-A (44) of PCM harness connector. Specification : below 1Ω 3) Is the measured resistance within specification? |
