Test 10D: Pump/Motor 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 .
  1. Ensure pump/motor is still actuating. Using DRB, read INPUT STATE of pump/motor output. If pump/motor is cycling between on and off, pump/motor circuit is operating properly at this time. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If pump/motor is not cycling on and off, go to next step.
  2. Using DRB, stop MOTOR PUMP actuation. Turn ignition off. Disconnect pump motor relay connector. Disconnect CAB 60-pin connector. Connect a jumper wire between chassis ground and Brown/White wire at pump/motor relay connector. Put DRB in ohmmeter mode. Using DRB, check resistance of CAB connector terminal No. 20 (Brown/White wire). If resistance is more than 5 ohms, repair open in Brown/White wire. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If resistance is less than 5 ohms, replace CAB. Perform TEST VER-1A: SYSTEM VERIFICATION TEST .
