Troubleshooting
Code Description
Code 5C! displays when the Electronic Control Unit (ECU) receives
an unusually high or low reading from the pressure transducer. A
diagnostic tool will specify which of the two conditions is responsible for
setting the code.
Initial troubleshooting steps involve checking for a shorted­to­ground or
an open pressure transducer circuit.
If the circuits check out OK, secondary causes could involve a faulty
transducer or a faulty Electronic Control Unit.
See “Troubleshooting Tips” on page 20 for general guidelines on system
diagnostics.
