Figure 516. Code 44 Schematic Drawing
Main code 44 indicates the ECU has detected a short-to-ground in a solenoid or its wiring. The DO NOT SHIFT
response is activated when some subcodes are detected, all solenoids are turned off, and the CHECK TRANS light
For subcodes 12, 13, 14, 15, 16, 22 neutral start is inoperable. Subcodes 21, 23, 24, and 26 do not
trigger the CHECK TRANS light.
Active Indicator Clearing Procedure:
Intermittent connections or lack of battery-direct power and ground connections may cause this and
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 517 for resistance values versus temperature.
