While driving yesterday, the tach, speedometer and fuel gauge just stopped working. Went through electrical schematics. Nothing in common with all three except ECM outputs. Checked to make sure all fuses were good. I started to trouble shoot fuel gauge. Have voltage going to sending unit. Jumpered out anti slosh module, still no indication. Hooked up OBD-2 scanner. Started and drove car and had both speedo and tach readings. This told me that ECM was good. At that point i took out the instrument cluster and checked for any obvious connector problems. Cleaned up all contacts, reconnected both harness connectors . Started car and everything worked again. Thought I would post in case this happens to anyone.
