With Lexus Hand-Held Tester

  1. Using tester connected to Data Link Connector No. 3 (DLC3), enter DATALIST mode. Test drive vehicle and check tachometer parameter. If parameter value changes with engine speed, replace combination meter. If parameter value does not change, go to next step.
  2. Check harness and connector between combination meter and ECM. Repair as necessary. If circuits are okay, repair ignition coil and/or wire harness.
