Control Module: Testing and Inspection















1. Turn the ignition switch to ON, and check the transmission control module terminal voltage, referring to the Terminal Voltage Chart illustrated.
2. If not correct, check or replace the component(s), wiring, and/or transmission control module.

NOTE: Use the ground of terminal 1J of the transmission control module when measuring terminal voltage, as an error may occur when the negative (-) lead of the circuit tester is connected to ground.
