Test TC-15C: Speed Control Solenoid Circuits Or SPEEDCONTROL Power Relay Circuits

NOTE: Perform TEST TC-15A  before proceeding. For connector terminal identification, see CONNECTOR IDENTIFICATION  . To identify referenced circuits and terminals, see WIRING DIAGRAMS  .
  1. Turn ignition off. Disconnect Powertrain Control Module (PCM) connectors. Inspect connectors and terminals for damage. Repair connectors and terminals as necessary and perform TEST SC-VER  . If connectors and terminals are okay, go to next step.
  2. Using scan tool in ohmmeter mode, check S/C power supply circuit resistance (Yellow/Red wire) between PCM Gray connector and S/C servo 4-pin connector. If resistance is less than 5 ohms, replace PCM and perform TEST SC-VER  . If resistance is 5 ohms or more, repair open S/C power supply circuit and perform TEST SC-VER  .
