1996 Subaru SVX LFACTORY OEM SERVICE PROCEDURE

Code 38 - Engine Torque Control

NOTE: For ECM harness connector terminal identification, see Figure.
  1. Turn ignition on. Using a DVOM, check voltage between ECM harness connector terminal A20 (backprobe) and ground. Voltage should be 5 volts or greater. If voltage is not as specified, go to next step. If voltage is as specified, check ECM harness connector terminals for good contact. Repair as necessary. If harness connector terminals are okay, replace ECM.
  2. Turn ignition off. Disconnect ECM and Transaxle Control Module (TCM) harness connectors. Using an ohmmeter, check resistance between ECM harness connector terminal A20 and TCM harness connector terminal C16 (Black/Yellow wire). Resistance should be zero ohms. If resistance is not as specified, repair circuit as necessary. If resistance is as specified, check TCM harness connector terminals for good contact. Repair as necessary. If harness connector terminals are okay, replace TCM.
