Test 11C - No Termination
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For appropriate wiring diagram, see WIRING DIAGRAMS
at end of article.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition off, and disconnect DRB-II. Disconnect Body Control Module (BCM). BCM is located behind right kick panel.
- Using an external ohmmeter, check resistance between BCM pins No. 14 and 15. See Fig 1 . If resistance is not 100-140 ohms, replace BCM. Perform VERIFICATION PROCEDURE VER-1.
- If resistance is 100-140 ohms, check resistance of CCD bus positive circuit (Violet/Brown wire) between BCM Black connector terminal No. 7 and CCD data link connector. If resistance is more than 5 ohms, repair open circuit in Violet/Brown wire. Perform VERIFICATION PROCEDURE VER-1.
- If resistance is less than 5 ohms, check resistance of CCD bus negative circuit (White/Black wire) between BCM Black connector terminal No. 20 and CCD data link connector. If resistance is more than 5 ohms, repair open circuit in White/Black wire. Perform VERIFICATION PROCEDURE VER-1.
- If resistance is less than 5 ohms, disconnect Powertrain Control Module (PCM). PCM is located between data link connector and battery, on fenderwell. Check resistance between PCM pins No. 46 and 26. If resistance is not 100-140 ohms, replace PCM. Perform VERIFICATION PROCEDURE VER-1.
- If resistance is 100-140 ohms, check resistance of CCD bus positive circuit (Violet/Brown wire) between PCM connector terminal No. 26 and CCD data link connector. If resistance is more than 5 ohms, repair open circuit in Violet/Brown wire. Perform VERIFICATION PROCEDURE VER-1.
- If resistance is less than 5 ohms, check resistance of CCD bus negative circuit (White/Black wire) between PCM connector terminal No. 46 and CCD data link connector.
- If resistance is more than 5 ohms, repair open circuit in White/Black wire. Perform VERIFICATION PROCEDURE VER-1. If resistance is less than 5 ohms, replace DRB-II cable or cartridge as necessary. Perform VERIFICATION PROCEDURE VER-1.
