With Lexus Hand-Held Tester

  1. Using tester connected to Data Link Connector No. 3 (DLC3), enter DATALIST mode. Test drive vehicle and check speedometer parameter. If parameter value changes with vehicle speed, replace combination meter. If parameter value does not change, go to next step.
  2. Check harness and connector between combination meter (instrument cluster) and ABS ECU. Repair as necessary. If circuits are okay, repair speed sensor and/or wire harness. See appropriate ANTI-LOCK/TRACTION CONTROL SYSTEMS article in BRAKES.
