Overdrive & TCC Off Command Signal Circuit Check

  1. Ensure ignition is off. Disconnect Cruise Control Electronic Control Unit (CC ECU) harness connector. Turn ignition on. Check voltage between ground and CC ECU harness connector terminal No. 3 (Pink/Blue wire on Esteem; Pink/Green wire on Sidekick 1.8L and X90). See Figure . Voltage should be 10-14 volts.
  2. If voltage is not within specification, check fuses, Pink/Blue or Pink/Green wires and harness connectors to Transmission Control Module (TCM). See WIRING DIAGRAMS  . Repair fuses, wiring or harness connectors as necessary. If fuses, wiring and connectors are okay, substitute known good Powertrain Control Module (PCM) and retest.
