1. Ignition OFF, disconnect the transmission 24-way inline harness connector, then the transmission 16-way in line harness connector at the
transmission, verify that a test lamp does not illuminate between the ignition voltage circuit terminal 12 and ground.
瀚慖f the test lamp illuminates, test the IGN voltage circuit for a short to voltage.
2. Ignition ON, verify that a test lamp illuminates between the ignition voltage circuit terminal 12 and ground.
瀚慖f the test lamp does not illuminate, test the ignition voltage circuit for a short to ground or an open/high resistance.
瀚慖f the circuit tests normal replace the control solenoid (w/body and TCM) valve assembly.

Circuit/System Description
This diagnostic applies to internal microprocessor integrity conditions within the engine control module (ECM) and the throttle actuator control
(TAC) system. This diagnostic also addresses if the ECM is not programmed.
The ECM monitors its ability to read and write to the memory. It also monitors a timing function. The ECM and the TAC processors are used to
monitor the TAC system data. Both processors monitor the other processors data to verify that the indicated APP calculation is correct. The ECM
