Test No. 3

  1. Check for battery voltage at each side of fuse No. 11. If battery voltage is not present, inspect fusible link No. 2. If battery voltage is present only at one side of fuse, replace faulty fuse. If battery voltage is present at both sides of fuse, go to next step.
  2. Disconnect ETACS-ECU harness connector. Check voltage between chassis ground and ETACS-ECU harness-side connector terminal No. 2 (Red/Black wire). If battery voltage is not present, inspect junction block connectors B-47 and B-75 (behind left side of dash). See WIRING DIAGRAMS  . Repair as necessary. If battery voltage is present, go to next step.
  3. Check continuity between chassis ground and ETACS-ECU harness-side connector terminal No. 1 (Black wire). If continuity is not present, check ETACS-ECU and junction block harness connectors. Repair as necessary. If continuity is present, replace ETACS-ECU.
