  1. Disconnect ECM/PCM connector A (49P).
  1. Connect the ECM/PCM connector A (49P) No. 6 terminal to body ground with a jumper wire.
  1. Turn the ignition switch to ON (II).
Do the fans run?
YES -
Check for loose wires or poor connections at ECM/PCM connector A (49P). If the connections are good, substitute a known-good ECM/PCM, and recheck. If the symptom/indication goes away, replace the original ECM/PCM .■
