Test 9A - Short To 5 Volts On Bus

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION . For appropriate wiring diagram, see WIRING DIAGRAMS .
CAUTION: Always turn ignition switch to OFF position before disconnecting or connecting any module connector.
  1. Using DRB-II, indicate whether a module is present or not. Disconnect Electronic Automatic Transaxle (EATX) controller connector. Connector is located on firewall on right side of engine compartment. Check connector, and clean or repair connector as necessary. If DRB-II does not display SHORT TO 5 VOLTS, replace EATX controller. Perform VERIFICATION TEST . If DRB-II displays SHORT TO 5 VOLTS, disconnect Single Board Engine Controller (SBEC) connector.
  2. Check connector, and clean or repair connector as necessary. Using an external ohmmeter, check resistance between terminals No. 6 (Violet/White wire) and No. 26 (Violet/Brown wire) at SBEC connector. If resistance is less than 1000 ohms, repair short in Violet/Brown and Violet/White wires. Perform VERIFICATION TEST .
  3. If resistance is more than 1000 ohms, check resistance between terminals No. 46 (White/Black wire) and No. 6 (Violet/White wire) of SBEC connector. If resistance is less than 1000 ohms, repair short in White/Black and Violet/Black wires. Perform VERIFICATION TEST .
  4. If resistance is more than 1000 ohms, turn ignition switch to ON position with engine off. If DRB-II does not display SHORT TO 5 VOLTS, replace SBEC. Perform VERIFICATION TEST . If DRB-II displays SHORT TO 5 VOLTS, disconnect compass/mini-trip module connector (if equipped). Connector is located in overhead console.
  5. If DRB-II does not display SHORT TO 5 VOLTS, replace compass/mini-trip module. If DRB-II displays SHORT TO 5 VOLTS, disconnect body controller Blue connector. Body controller is located under left side of instrument panel.
  6. If DRB-II does not display SHORT TO 5 VOLTS, replace body controller. Perform VERIFICATION TEST . If DRB-II displays SHORT TO 5 VOLTS, replace instrument cluster. Perform VERIFICATION TEST .
