WTEC III ELECTRONIC CONTROLS TROUBLESHOOTING MANUAL
CODE 45 XX -- OPEN CONDITION IN SOLENOID CIRCUIT (Figure 518)
Main code 45 indicates the ECU has detected either an open circuit condition in a solenoid coil or the wiring to that
solenoid. The DO NOT SHIFT response is activated when some subcodes are detected, all solenoids are turned
off, and the CHECK TRANS light is illuminated.

NOTE:
Intermittent connections or lack of battery-direct power and ground connections may cause this and
other codes.
NOTE:
Before troubleshooting, read Paragraph 56. Also, check battery and ECU input voltages.
PROBING THE CONNECTOR
When testing the control system from the feedthrough connector with the internal harness connected, the resistance
of each solenoid can be checked using a VOM. Refer to Figure 519 for solenoid resistance values versus
temperature.
