NOTE:
For connector terminal ID, see CONNECTOR IDENTIFICATION
and WIRING DIAGRAMS
. Perform TEST VER-2A - VERIFICATION PROCEDURE
after each repair.
CAUTION:
Always turn ignition off prior to disconnecting any module connector.
- Turn ignition off. Disconnect compass/mini trip module 6-pin connector. Using scan tool in ohmmeter mode, measure resistance on terminal No. 3 (Black/Light Green wire). If resistance is 5 ohms or more, repair open Black/Light Green wire. If resistance is less than 5 ohms, go to next step.
- Turn ignition on. Using scan tool in voltmeter mode, measure voltage on terminal No. 4 (Black/Orange wire). If voltage is 10 volts or less, repair open Black/Orange wire. If voltage is more than 10 volts, go to next step.
- Connect jumper wire between compass/mini trip module 6-pin connector, terminal No. 1 (White/Black wire) and ground. Using scan tool, select BODY, BODY COMPUTER, then SYSTEM TEST. Perform CCD BUS test. If scan tool does not display BUS SHORT TO GROUND, repair open White/Black wire. If scan tool displays BUS SHORT TO GROUND, go to next step.
- Move jumper wire to terminal No. 6 (Violet/Brown wire). Perform CCD BUS test. If scan tool does not display BUS SHORT TO GROUND, repair open Violet/Brown wire. If scan tool displays BUS SHORT TO GROUND, replace compass/mini trip module.
