Pinout Values and Diagnostic Parameters

Test Readings, SRM

The following contains directions and readings for testing the control module.

Remember:
- Observe the test criteria. Use common sense when assessing the test results.
- The test readings presented here are with the ignition ON unless stated otherwise.
- Check these points:
- Check first that the control module is receiving power and is grounded.
- Then check all sensor inputs and signals from other systems.
- Finally, check the control module outputs. Remember that the test readings are not a confirmation of whether the actuator is in working order.
- If a test reading is incorrect, use the wiring diagram to locate the leads, connectors or components that need to be checked further.
- Specified test readings are for a calibrated Fluke 88/97.
- Test values show the signal pulse ratio and pulse width respectively. A scan tool with pulse ratio and pulse width measurement respectively must be used.

Note: All units on the I and P buses send signals.
