Test DQ: Step 12

12) Checking FIPL Circuit Continuity  Turn ignition switch to "OFF" position. Wait 10 seconds. With the FIPL connector and ECA 60-pin connector disconnected, inspect for damaged pins, corrosion, or loose wires. Repair as necessary. Install breakout box. Connect ECA to breakout box. Set DVOM at 200 ohm scale. Measure resistance between FIPL circuit at the FIPL sensor harness connector and test pin No. 47 at the breakout box. If the resistance is less than 5 ohms go to the next step. If the resistance is greater than 5 ohms, go to repair open circuit, remove breakout box and repeat QUICK TEST.
