2004.5 Spectra Technology
The inputs to the A/T side of the PCM include the
driver shifter/range switch, input and output speed
sensor, A/T oil temperature, and A/T control relay for
shift solenoids A to D.
Output controls include the ground side of shift
solenoid A, B, C, and D and the TCC solenoid.
When self-diagnostic test fails and a DTC is set, the
PCM turns the MIL ONand the A/T goes into failsafe
mode.
The 16-pin DLC connector, driver side under IP,
provides valuable A/T operational information and
diagnostic testing through the Hi-Scan Pro.
