Diagnostic Procedure

  1. If FREEZE FRAME DATA has been recorded, go to next step. If FREEZE FRAME DATA has not been recorded, record FREEZE FRAME DATA. Go to next step.
  2. Verify Related Repair Information Availability -  Check for related Service Bulletins and/or on-line repair information availability. If any related repair information is available, perform repair or diagnosis according to available repair information. If vehicle is not repaired, go to next step. If related repair information is not available, go to next step.
  3. Inspect VTCS Solenoid Valve Connector For Poor Connection -  Turn ignition off. Inspect for poor connection (such as damaged, pulled-out pins, corrosion). If malfunction is not present, go to next step. If malfunction is present, repair or replace terminal. After repair, go to step  7.
  4. Inspect VTCS Solenoid Valve -  Perform VTCS Solenoid Valve Inspection. Refer to VARIABLE TUMBLE CONTROL SYSTEM - MAZDA6 (2.3L) under AIR INDUCTION SYSTEMS in SYSTEM & COMPONENT TESTING - MAZDA6, MIATA, MPV, PROTEGE & PROTEGE5 article. If VTCS solenoid valve is okay, go to next step. If VTCS solenoid valve is faulty, replace VTCS solenoid valve. After repair, go to step  7.
  5. Inspect PCM Connector For Poor Connection -  Inspect for poor connection (such as damaged, pulled-out terminals, corrosion) at PCM 30-pin harness connector terminal "4T" (Blue/Orange wire). If malfunction is not present, go to next step. If malfunction is present, repair or replace terminal. After repair, go to step  7.
  6. Inspect VTCS Solenoid Valve Control Circuit For Short To Power -  Remove VTCS solenoid valve. Turn ignition on, engine off. Measure voltage between PCM 30-pin harness connector terminal "4T" (Blue/Orange wire) and body ground. See Figure. If battery voltage is present, repair short circuit to power in Blue/Orange wire between PCM 30-pin harness connector terminal "4T" and VTCS solenoid valve harness connector terminal "B". See ENGINE PERFORMANCE in SYSTEM WIRING DIAGRAMS article in ELECTRICAL. After repair, go to next step.
  7. Verify Trouble Shooting Of DTC P2010 Is Completed -  Make sure to reconnect all disconnected connectors. Clear DTC from PCM memory using WDS or equivalent. Turn ignition off. Start engine and warm up completely. If PENDING CODE of same DTC is not present, go to next step. If PENDING CODE of same DTC is present, replace PCM. For PCM removal and installation, see POWERTRAIN CONTROL MODULE under COMPUTERIZED ENGINE CONTROLS in REMOVAL & INSTALLATION article. After repair, go to next step.
  8. Verify After Repair Procedure -  Using scan tool, perform After Repair Procedure. See AFTER REPAIR PROCEDURE . If any DTCs are present, go to appropriate DTC inspection. Refer to DIAGNOSTIC TROUBLE CODE DEFINITIONS . If no DTCs are present, trouble shooting is complete.
