Diagnostic Procedure;

1. Figure 1, with the ignition key off; remove and jump the relay with a fused link . Back probe the TCM or Single New Generation Computer (NGC) connected.

2. Following figures unplug the TCM or Single New Generation Computer (NGC) with the ignition key off .

3. Jump voltage (always through a fusible link) across the connector pins found in the wire schematic for the vehicle being worked on.

4. Check the return voltage (source voltage) at the pins shown in each diagram.

Note: If necessary the positive meter lead can be moved to the amps jack then with the meter switched to DC amps the same circuits can be checked for load.

Figure 1 & 2: Diagrams for the 41TE (A604) transaxle found in vehicles from 1989 to 2002 the only difference is the additional ground pins used on the 1989 to 1995 models.

Note: When working on Mitsubishi vehicles with the 41TE (A604) transaxle from 1995 to 1998, the numeric order of the TCM connector pin configuration is reversed (shown in last figure).

The following diagrams are derived from information that has been carefully compiled from industry sources known for their reliability and should be accurate. Always verify the circuits be tested with factory manuals whenever possible.
