Test 21B - Testing Compass/Mini-Trip Module For No Response
NOTE:
For connector terminal identification, see BODY CONTROL SYSTEM CONNECTORS under DIAGNOSTIC PROCEDURE. For wiring diagrams, see appropriate chassis wiring diagram in the WIRING DIAGRAMS Section.
- Turn ignition switch to OFF position. Put DRB-II in ohmmeter mode. Probe terminal No. 5 (Black/Orange wire) of compass/mini-trip module connector. If resistance is more than 5 ohms, repair open Black/Orange wire. Perform VERIFICATION TEST. If resistance is less than 5 ohms, disconnect DRB-II.
- Using an external ohmmeter, check resistance at Violet/Brown wire between terminals No. 1 of CCD bus diagnostic connector and No. 12 of compass/mini-trip module connector. If resistance is more than 5 ohms, repair open in Violet/Brown wire. Perform VERIFICATION TEST.
- If resistance is less than 5 ohms, check resistance between terminals No. 6 (White/Black wire) of CCD bus diagnostic connector and No. 11 (White/Black wire) of compass/mini-trip module connector. If resistance is more than 5 ohms, repair open in White/Black or White/Gray wire. Perform VERIFICATION TEST. If resistance is less than 5 ohms, replace compass/mini-trip module. Perform VERIFICATION TEST.
