EATX Message Mismatch

NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.
  1. With the DRBIII, read DTCs. If the DRBIII displays EATX BUS MESSAGE NOT RECEIVED refer to the communications section of the symptom identification table for related symptoms. See SYMPTOM INDEX  table under SELF-DIAGNOSTIC SYSTEM. If the DRBIII does not display EATX BUS MESSAGE NOT RECEIVED, go to the next step.
  2. With the DRBIII in Cluster Type, ensure that the instrument cluster is correctly configured. If the instrument cluster is configured correctly, replace the instrument cluster. See INSTRUMENT CLUSTER under REMOVAL & INSTALLATION in appropriate ANALOG INSTRUMENT PANELS article. If the instrument cluster is not configured correctly, with the DRBIII, configure the instrument cluster.
