Location of the solenoids (1) Forward high solenoid (2) Reverse solenoid (3) Forward low solenoid (4) The solenoid for the First gear and the second gear (5) The solenoid for the third gear (6) The solenoid for the fourth gearEnsure that the diagnostic code is on hold. Ensure that the diagnostic code is active.Use table 1 in order to determine the solenoids that are energized. Table 1 identifies the solenoids that are energized for each position on the shift lever.
Table 1
Information about the Solenoids    
Solenoid     Number of the Solenoid (2)     Number of the Contact

( 2 ) This number is used in order to identify the solenoids in the manual.
( 1 ) "Solenoid Group A"
( 3 ) "Solenoid Group B"FMI 06 is recorded when the transmission electronic control module senses a short. The short is to ground.
Check for a short to ground.
Turn the key start switch to the OFF position.
Disconnect the machine harness from the control module.
Measure the continuity from contact 2 to contact 35.The results of the preceding procedure are in the following list:
There is not continuity. The solenoid harness does not have a short to ground. Connect the machine's harness. Verify that the active fault is present. If the active fault is present the transmission electronic control module is faulty. Replace the transmission electronic control module. Refer to Testing and Adjusting, "Electronic Control Module (ECM) - Replace".
There is continuity. The solenoid harness has a short to ground or the solenoid has a short to ground. Repair the harness or replace the harness or the solenoid.
