Integra (Using DVOM)

  1. Check fuse No. 15 (7.5-amp) in underdash fuse/relay box. Disconnect VSS 3-pin harness connector located on top rear of transaxle. Connect VSS Test Harness (07LAJ-PT3020A) to VSS 3-pin harness connector only. See Fig 1 . Check continuity between ground and Red test harness clip. If continuity is present, go to next step. If continuity is not present, repair open in Black wire between ground and VSS 3-pin harness connector located at right rear of engine.
  2. Connect positive DVOM probe to White test harness clip, and connect negative DVOM probe to Red test harness clip. See Fig 1 . Turn ignition on. If battery voltage is present, go to next step. If battery voltage is not present, repair open in Black/Yellow wire between VSS 3-pin harness connector and fuse No. 15 (7.5-amp).
  3. Disconnect White test harness clip. Connect Green test harness clip to positive DVOM probe. If 5 volts or more is present, go to next step. If voltage is not as specified, repair open in wire between PCM 31-pin connector terminal No. 23 (Orange wire) and VSS 3-pin connector terminal No. 3 (Blue/White wire).
  4. Turn ignition off. Connect other end of VSS Test Harness (07LAJ-PT3020A) to VSS connector. Raise and support front of vehicle. Place transaxle in Neutral and turn ignition on. Block left front wheel. While observing voltmeter, slowly rotate right front wheel. If voltage pulses between zero and about 5 volts, go to next step. If voltage does not pulse between zero and about 5 volts, replace VSS.
  5. Disconnect instrument panel 16-pin harness connector. Measure voltage between ground and instrument panel 16-pin harness connector terminal No. 6 (Orange wire). While observing voltmeter, slowly rotate right front wheel. If voltage pulses between 0 and about 5 volts, replace speedometer. If voltage does not pulse between 0 and 5 volts, repair open in Orange and Blue/White wire between VSS 3-pin connector and instrument panel 16-pin harness connector.
