Control Relay (1.8L)

1994 Plymouth Laser RS Turbo, AWD, AutomaticSECTION Control Relay (1.8L)
  1. Control relay is located on right side of center console. Disconnect control relay connector. Using an ohmmeter, measure resistance between control relay terminals No. 3 and 5, and terminals No. 2 and 5. See Fig 1 . Resistance should be about 95 ohms. If resistance is about 95 ohms, go to next step. If resistance is not as specified, replace relay.
  2. Measure resistance between control relay terminals No. 6 and 7. Resistance should be about 35 ohms. If resistance is about 35 ohms, go to next step. If resistance is not as specified, replace relay.
  3. Check for continuity between terminals No. 6 and 8 in both directions. Continuity should exist in one direction only (circuit is equipped with diode). If continuity is as specified, go to next step. If continuity is not as specified, replace relay.
  4. Using a 12-volt power source, connect positive lead to terminal No. 7 and negative lead to terminal No. 6. Using an ohmmeter, check for continuity between terminals No. 1 and 4. Continuity should exist. Disconnect negative lead of power source from terminal No. 6. Continuity should no longer exist. If continuity is as specified, go to next step. If continuity is not as specified, replace relay.
  5. Connect power source positive lead to terminal No. 8 and negative lead to terminal No. 6. Using an ohmmeter, check for continuity between terminals No. 2 and 4. If continuity exists, go to next step. If continuity does not exist, replace relay.
  6. Disconnect power source negative lead from terminal No. 6. Check for continuity between terminals No. 2 and 4. Continuity should not exist. If continuity exists, replace relay.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
