Test 11B - No Termination
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION in TESTS W/CODES - BODY CONTROL COMPUTER
article. For wiring diagram, see the appropriate WIRING DIAGRAMS
article in the ENGINE PERFORMANCE section. After each repair, perform TEST VER-1.
- WIRING DIAGRAMS - 2.5L TBI
- WIRING DIAGRAMS - 2.5L FLEXIBLE FUEL
- WIRING DIAGRAMS - 3.0LCAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
- Turn ignition off. Disconnect Powertrain Control Module (PCM). PCM is located between Data Link Connector (DLC) and battery, on fenderwell.
- Using an external ohmmeter, check resistance between PCM terminals No. 26 and 46. If resistance is not 100-140 ohms, replace PCM.
- If resistance is 100-140 ohms, check resistance of Violet/Brown wire between PCM connector terminal No. 26 and (backprobe) DLC terminal No. 6. If resistance is more than 5 ohms, repair open Violet/Brown wire.
- If resistance is less than 5 ohms, check resistance of White/Black wire between PCM connector terminal No. 46 and (backprobe) DLC terminal No. 4. If resistance is more than 5 ohms, repair open White/Black wire.
- If resistance is less than 5 ohms and vehicle is not equipped with 41TE transaxle, go to step 9). If resistance is less than 5 ohms and vehicle is equipped with 41TE transaxle, disconnect Transmission Control Module (TCM). TCM is located on left side of engine compartment, near cowl. Check resistance between TCM terminals No. 5 and 44. If resistance is not 100-140 ohms, replace TCM.
- If resistance is 100-140 ohms, check resistance of Violet/Brown wire between TCM connector terminal No. 43 and DLC terminal No. 6. If resistance is more than 5 ohms, repair open Violet/Brown wire.
- If resistance is less than 5 ohms, check resistance of White/Black wire between TCM connector terminal No. 4 and DLC terminal No. 4. If resistance is more than 5 ohms, repair open White/Black wire.
- If resistance is less than 5 ohms and vehicle is not equipped with a traveler, replace scan tool cable or cartridge as necessary. If vehicle is equipped with a traveler, go to next step.
- Disconnect traveler module. Traveler module is located behind right side of dash, below glove box. Check resistance between traveler module terminals No. 1 and 2. See Figure .
- If resistance is not 100-140 ohms, replace traveler. If resistance is 100-140 ohms, check resistance of Violet/Brown wire between traveler module connector terminal No. 1 and DLC terminal No. 6. If resistance is more than 5 ohms, repair open Violet/Brown wire.
- If resistance is less than 5 ohms, check resistance of White/Black wire between traveler module connector terminal No. 2 and DLC terminal No. 4. If resistance is more than 5 ohms, repair open White/Black wire. If resistance is less than 5 ohms, replace scan tool cable or cartridge as necessary.
