Diagnostic Circuit

Connect tester to ARC/EVO connector at right front shock tower. Check resistance between pins No. 30 and No. 46 at 60-pin connector at ARC module. Check resistance with tester button depressed and released. If resistance always more than 1000 ohms, repair open in Gray/Red wire (Circuit No. 844), or poor contact at connector. If more than 1000 ohms released and less than 10 ohms depressed, replace ARC module. Less than 10 ohms always, check STAR Tester.
