Test 13K - No Bus Bias
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION
. For wiring diagrams, see appropriate article in ENGINE PERFORMANCE:
- WIRING DIAGRAMS - 3.3L
- WIRING DIAGRAMS - 3.5L
- After each repair, perform TEST VER-1.CAUTION: Always turn ignition switch to OFF position before disconnecting or connecting any module connector.
- Turn ignition off. Disconnect traveler module. Traveler module is located behind right side of dash, below glove box. Using an external ohmmeter, check resistance between traveler module terminals No. 1 and 2.
- 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 Data Link Connector (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, reconnect scan tool. Using scan tool in voltmeter mode, check voltage on traveler connector terminal No. 5 (White wire). If voltage is less than 10 volts, repair White wire as necessary.
- If voltage is more than 10 volts, using scan tool in ohmmeter mode, check resistance of visual message center connector ground circuit (Black wire). If resistance is more than 5 ohms, repair open Black wire. If resistance is less than 5 ohms, replace traveler module.
NOTE:
A break in test sequence occurs at this point. No test procedures have been omitted.
