  1. Disconnect scan tool. Ensure ignition is on, engine off. Using an external voltmeter, measure voltage between ground and DLC terminal No. 3 (Violet/Brown wire). If voltage is 2.3-2.6 volts, go to next step. If voltage is not 2.3-2.6 volts, go to step  3 .
  2. Ensure ignition is on, engine off. Measure voltage between ground and DLC terminal No. 11 (White/Black wire). If voltage is not 2.3-2.6 volts, go to next step. If voltage is 2.3-2.6 volts, replace scan tool cable or scan tool. Perform VERIFICATION TEST: VER-2A  .
  3. Remove instrument cluster. Connect jumper wire between ground and DLC terminal No. 11 (White/Black wire). Using external ohmmeter, measure resistance between ground and terminal No. 1 (White/Black wire) on right instrument cluster connector. If resistance is less than 5 ohms, go to next step. If resistance is 5 ohms or greater, repair open White/Black wire. Perform VERIFICATION TEST: VER-2A  .
  4. Disconnect jumper wire. Connect jumper wire between ground and DLC terminal No. 3 (Violet/Brown wire). Measure resistance between ground and terminal No. 2 (Violet/Brown wire) on right instrument cluster connector. If resistance is less than 5 ohms, replace instrument cluster.
