Test F: Tachometer Inoperative

WARNING: This page is about a different car, the 2001 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
  1. Using New Generation Star (NGS) tester, select instrument cluster TACHOMETER active command. Trigger TACHOMETER active command and scroll in increments of 10%. Monitor tachometer. Tachometer should increase in increments of about 800 RPM for each 10% change. If tachometer is not as specified, go to next step. If tachometer is as specified, repair tachometer concern. See appropriate SELF-DIAGNOSTICS article in ENGINE PERFORMANCE.
  2. Disconnect all instrument cluster harness connectors. Inspect for corrosion or pushed out pins. Connect all instrument cluster harness connectors. Operate system and verify if concern still exists. If concern still exists, replace instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. If concern does not exist, system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
