CODE 44 XX -- SHORT-TO-GROUND IN SOLENOID CIRCUIT

WTEC III ELECTRONIC CONTROLS TROUBLESHOOTING MANUAL

CODE 44 XX -- SHORT-TO-GROUND IN SOLENOID CIRCUIT (Figure 516)

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

is illuminated.

NOTE:

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.

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 517 for resistance values versus temperature.
