Test 11E - No Termination
NOTE:
Test procedures skip from TEST 10A to TEST 11E. No test procedures have been omitted.
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For appropriate wiring diagram, see WIRING DIAGRAMS
section at the end of this article.
CAUTION:
Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition off. Disconnect Body Control Module (BCM) connectors. Using an external ohmmeter, check resistance between BCM pins No. 7 and 20. See Fig 1
. If resistance is not 100-140 ohms, rep lace BCM. Perform TEST VER-1.
NOTE: DO NOT disconnect scan tool from Data Link Connector (DLC) when performing next step through end of test procedure.
- If resistance is 100-140 ohms, check resistance of CCD BUS positive circuit (Violet/Brown wire) between BCM Blue connector terminal No. 7 and Data Link Connector (DLC). If resistance is more than 5 ohms, repair open Violet/Brown wire. Perform TEST VER-1.
- If resistance is less than 5 ohms, check resistance of CCD BUS negative circuit (White/Black wire) between BCM Blue connector terminal No. 20 and DLC. If resistance is more than 5 ohms, repair open White/Black wire. Perform TEST VER-1.
- If resistance is less than 5 ohms, disconnect Powertrain Control Module (PCM) connector. Check resistance between PCM pins No. 26 and 46. If resistance is not 100-140 ohms, replace PCM. Perform TEST 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 DLC. If resistance is more than 5 ohms, repair open Violet/Brown wire. Perform TEST 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 DLC.
- If resistance is more than 5 ohms, repair open White/Black wire. Perform TEST VER-1. If resistance is less than 5 ohms, replace scan tool cable or cartridge as necessary. Perform TEST VER-1.
