Checking Diagnostic Circuit Resistance

  1. Connect Star Tester to ARC/EVO diagnostic test connector, located at right front shock tower. Using DVOM, check resistance between pins No. 30 and 46 at ARC module 60-pin connector. Check and record resistance with tester button depressed and released.
  2. If resistance is greater than 1000 ohms in both tester button positions, repair open in Gray/Red wire (circuit No. 844) or repair poor contact at diagnostic test connector. If resistance is greater than 1000 ohms when button is released and less than 10 ohms when button is depressed, replace ARC module. If resistance is always less than 10 ohms, check Star Tester for malfunction.
