WARNING: This page is about a different car, the 1997 Eagle Vision, 1997 Dodge Intrepid, 1997 Chrysler LHS, and 1997 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform SYMPTOM ID TEST 1A
- IDENTIFYING VEHICLE EQUIPMENT & SYSTEM PROBLEMS or TEST 81A before proceeding with this test. For connector terminal ID, see CONNECTOR IDENTIFICATION
. For wiring schematics, see WIRING DIAGRAMS
in this article. Perform TEST VER-1 - VERIFICATION PROCEDURE
after each repair.
CAUTION:
Always turn ignition off prior to disconnecting any module connector.
- Turn ignition off. Disconnect OTIS 4-pin connector. Using scan tool in ohmmeter mode, measure resistance at terminal No. 3 (Black/Light Green wire) on OTIS 4-pin connector. If resistance is 5 ohms or greater, repair open Black/Light Green wire. If resistance is less than 5 ohms, go to next step.
- Turn ignition on. Using scan tool in voltmeter mode, measure voltage at terminal No. 4 (Dark Blue/White wire) on OTIS 4-pin connector. If voltage is 10 volts or less, repair open Dark Blue/White wire. If voltage is more than 10 volts, go to next step.
- Connect jumper wire between ground and terminal No. 1 (White/Black wire) on OTIS 4-pin connector. Using scan tool, read CCD bus status. If scan tool does not display BUS SHORTED TO GROUND, repair open White/Black wire. If scan tool displays BUS SHORTED TO GROUND, disconnect jumper wire. Go to next step.
- Connect jumper wire between ground and terminal No. 2 (Violet/Brown wire) on OTIS 4-pin connector. If scan tool does not display BUS SHORTED TO GROUND, repair open Violet/Brown wire. If scan tool displays BUS SHORTED TO GROUND, replace OTIS module.
