Test 11F - No Termination (Exc Wrangler)

NOTE: For connector terminal identification, see CONNECTOR IDENTIFICATION  in this article. 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.
  1. Turn ignition off. Disconnect scan tool from Data Link Connector (DLC). Disconnect Powertrain Control Module (PCM) connector. Using an external ohmmeter, check resistance between PCM pins No. 26 and 46. If resistance is not 100-140 ohms, replace PCM. Perform TEST VER-1 .
  2. 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 .
  3. If resistance is less than 5 ohms, check resistance of CCD BUS negative circuit (White/Black wire on XJ body; White/Gray wire on ZJ body) between PCM connector terminal No. 46 and DLC. If resistance is more than 5 ohms, repair open CCD BUS negative wire. Perform TEST VER-1 .
  4. If resistance is less than 5 ohms and vehicle is not equipped with anti-lock brakes, go to step 8). If resistance is less than 5 ohms and vehicle is equipped with anti-lock brakes, disconnect Controller Anti-Lock Brake (CAB) module connector. Check resistance between CAB pins No. 23 and 42. If resistance is not 100-140 ohms, replace CAB. Perform TEST VER-1 .
  5. If resistance is 100-140 ohms, check resistance of CCD BUS positive circuit (Violet/Brown wire) between CAB connector terminal No. 23 and DLC. If resistance is more than 5 ohms, repair open Violet/Brown wire. Perform TEST VER-1 .
  6. If resistance is less than 5 ohms, check resistance of CCD BUS negative circuit (White/Black wire on XJ body; White/Gray wire on ZJ body) between CAB connector terminal No. 42 and DLC. If resistance is more than 5 ohms, repair open CCD BUS negative wire. Perform TEST VER-1 . If resistance is less than 5 ohms, go to next step.
  7. If vehicle is not equipped with a Vehicle Theft Security System (VTSS) module, replace scan tool cable or cartridge as necessary. Perform TEST VER-1 . If vehicle is equipped with a VTSS module, go to next step.
  8. Disconnect VTSS module connector. Check resistance between VTSS module pins No. 1 and 2. See Fig 1.

    G95H27323
  9. If resistance is not 100-140 ohms, replace VTSS module. Perform TEST VER-1 . If resistance is 100-140 ohms, check resistance of CCD BUS positive circuit (Violet/Brown wire) between VTSS module connector terminal No. 2 and DLC. If resistance is more than 5 ohms, repair open Violet/Brown wire. Perform TEST VER-1 .
  10. If resistance is less than 5 ohms, check resistance of CCD BUS negative circuit (White/Black wire on XJ body; White/Gray wire on ZJ body) between VTSS module connector terminal No. 1 and DLC.
  11. If resistance is more than 5 ohms, repair open CCD BUS negative wire. Perform TEST VER-1 . If resistance is less than 5 ohms, replace scan tool cable or cartridge as necessary. Perform TEST VER-1 .
NOTE: Test procedures skip from TEST 11F to TEST 11J. No test procedures have been omitted.
