Test 9E: Modulator Circuit
WARNING: This page is about a different car, the 1994 Plymouth Sundance, 1994 Plymouth Acclaim, 1994 Dodge Spirit, 1994 Dodge Shadow, and 1994 Chrysler LeBaron. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For connector terminal identification, refer to CONNECTOR IDENTIFICATION . For wiring diagrams, refer to WIRING DIAGRAMS .
- Turn ignition off. Disconnect CAB 60-pin connector. Turn ignition on. Put DRB in voltmeter mode. Using DRB, check voltage on CAB connector terminal No. 48 (Dark Green/Light Blue wire). If voltage is present, repair short to battery in Dark Green/Light Blue wire. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If voltage does not exist, go to next step.
- Turn ignition off. Put DRB in ohmmeter mode. Using DRB, check resistance of Dark Green/Light Blue wire at modulator assembly 10-pin connector. If resistance is less than 5 ohms, repair short to ground in Dark Green/Light Blue wire. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If resistance is more than 5 ohms, go to next step.
- Connect a jumper wire between chassis ground and CAB 60-pin connector terminal No. 48 (Dark Green/Light Blue wire). Using DRB, check resistance of Dark Green/Light Blue wire at modulator assembly 10-pin connector. If resistance is less than 5 ohms, replace CAB. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If resistance is more than 5 ohms, repair open Dark Green/Light Blue wire. Perform TEST VER-1A: SYSTEM VERIFICATION TEST .
