9-3 Arc/Aero (9440) L4-2.0L Turbo (2.0 T) (2004)
Scope
Following are readings and directions for measuring signals and levels of the transmission control module. Pin numbers missing in the table are not
used.
Remember
-
Observe the test criteria and use common sense when assessing the test results.
-
The test reading presented here are with the ignition ON unless stated otherwise.
-
Check first that the control module is receiving power and is grounded.
-
Then check all the sensor inputs and signals from other systems.
-
Finally, check the control module outputs. Remember that test values do not confirm whether the actuator is in working order.
-
If any of the test readings is incorrect, use the wiring diagram to locate the leads, connectors or components that should be checked further.
-
Specified test readings are for a calibrated Fluke 88/97.
-
Test readings %(+) and ms(+) show the signal pulse ratio and pulse width respectively. A scan tool that can measure pulse ratio and pulse width
respectively must be used. The sign indicates a positive trigger pulse, TRIG+.
