Pinout Values and Diagnostic Parameters

Scope
The following tables contain specified values and directions for measuring signals and levels on the automatic transmission control module.

Points to remember:
- Observe the test conditions, use your common sense when judging the readings obtained.
- The specified values are with the ignition in position ON unless stated otherwise.
- First check that the control module is supplied with current and grounded.
- Then check all sensor inputs and signals from other systems.
- Finally, check the control module inputs. Remember that the test readings do not indicate whether or not the actuator is in working order.
- If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components which ought to be checked more thoroughly.
- The specified test readings refer to those obtained with a calibrated Fluke 88/97.
- Test readings %(+) and ms(+) indicate the signal's pulse ratio and pulse duration. A test instrument capable of measuring pulse ratio and pulse width must be used. The sign denotes a positive trigger pulse, TRIG+. vehicle speed reading can be obtained with the diagnostics instrument, command menu "Read functions" and "Output speed".
