Test 19A - Not Receiving Bus Messages Correctly On Bus

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS .
  1. If DRB-II is not connected to correct diagnostic connector, connect DRB-II to CCD bus diagnostic connector. Perform VERIFICATION TEST . If DRB-II is connected to CCD bus diagnostic connector, turn ignition switch to OFF position. Disconnect instrument cluster connector. Check connector, and clean or repair connector as necessary.
  2. Using an external ohmmeter, check resistance of White/Black wire between terminals No. 6 of CCD bus diagnostic connector and No. 9 at instrument cluster connector. If resistance more than 5 ohms, repair open White/Black wire. Perform VERIFICATION TEST .
  3. If resistance is less than less 5 ohms, reconnect instrument cluster connector. Turn ignition switch to ON position. If DRB-II displays NOT RECEIVING BUS MESSAGES CORRECTLY, replace instrument cluster. Perform VERIFICATION TEST . If DRB-II does not display NOT RECEIVING BUS MESSAGES CORRECTLY, perform TEST 20A .
