determine which wiring assembly is being used.
This is not a complete list of all fuses that may blow. Vehicle design differences make it impossible to list every possible circuit configuration that may
occur. Consult the electrical diagrams for the vehicle you are servicing to see if additional fuses may be affected.

*If the white wire shorts, three different conditions may occur depending on which wiring assembly is used on a particular transmission:
TCC ENABLED
This may occur if the transmission is over
temperature and there is a short in the white wire between the TCC and the TCC switch.
TCC ENABLED
This may occur if there is a short between the
IN SECOND-
temperature switch and the ECM.
FOURTH
ROUGH ENGINE
If the transmission has a fourth gear switch and
there is a short between the switch and the ECM, the ECM will always receive a signal that the transmission
is in fourth gear. This may affect engine performance if spark timing depends on transmission gear
information.
