Test NS-6B - Correcting No Response Condition
WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For connector terminal identification, see CONNECTOR IDENTIFICATION DIRECTORY TABLE
. For wiring diagram, see WIRING DIAGRAMS
section. After each repair, perform TEST VER-1
.
- If ignition is not on when NO RESPONSE message is displayed, turn ignition on to get a response. If ignition is on when NO RESPONSE message is displayed, turn ignition off. Go to next step.
- Disconnect DRB from Data Link Connector (DLC). Disconnect Powertrain Control Module (PCM) connector. PCM is located under air cleaner. Using an external ohmmeter, check resistance between DLC terminal No. 5 (Pink wire) and chassis ground. If resistance is less than 5 ohms, repair short to ground in Pink wire. If resistance is more than 5 ohms, go to next step.
- Check resistance between DLC terminal No. 1 (Light Green wire) and chassis ground. If resistance is less than 5 ohms, repair short to ground in Light Green wire. If resistance is more than 5 ohms, go to next step.
- Connect a jumper wire between DLC terminal No. 5 (Pink wire) and chassis ground. Using DRB in ohmmeter mode, check resistance of PCM connector terminal No. 25 (Pink wire). If resistance is more than 5 ohms, repair open Pink wire. If resistance is less than 5 ohms, go to next step.
- Disconnect jumper wire. Connect jumper wire between DLC connector terminal No. 1 (Light Green wire) and ground. Using DRB, check resistance of PCM connector terminal No. 45 (Light Green wire). If resistance is more than 5 ohms, repair open Light Green wire. If resistance is less than 5 ohms, go to next step.
- Connect DRB to a functional DLC on another vehicle. Turn ignition on. Using DRB, attempt to read trouble codes. If DRB does not display NO RESPONSE, replace initial vehicle's PCM. If DRB displays NO RESPONSE, substitute another DRB cartridge. Go to next step.
- Using DRB, attempt to read trouble codes. If DRB does not display NO RESPONSE, replace DRB cartridge. If DRB displays NO RESPONSE, substitute another DRB adapter cable. Using DRB, attempt to read trouble codes. If DRB does not display NO RESPONSE, replace DRB adapter cable. If DRB displays NO RESPONSE, repair or replace DRB.
