Scan Tool Reference

Control Module References (See: Testing and Inspection/Programming and Relearning) for scan tool information

Circuit/System Verification

Ignition ON, command the appropriate actuator in both directions with a scan tool. The scan tool door position parameter reading should be

between 3 and 253 counts.

Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the appropriate actuator.

2. Test for less than 1 ohm between the low reference circuit terminal 7 and ground.

瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance.

3. Ignition ON, test for 4.8-5.2 volts between the 5-volt reference circuit terminal 10 and ground.

瀚慖f less than the specified range, test the 5-volt reference circuit for a short to ground or an open/high resistance.

瀚慖f greater than the specified range, test the 5-volt reference circuit for a short to voltage.

4. Verify the appropriate scan tool parameter is less than 4 counts.

瀚慖f greater than the specified range, test the signal circuit terminal 9 for a short to ground. If the circuit tests normal, replace the HVAC

control module.

5. Install a 3-amp fused jumper wire between the signal circuit terminal 9 and the low reference circuit terminal. Verify the appropriate scan

tool parameter is greater than 250 counts.

瀚慖f less than the specified range, test the signal circuit for a short to voltage or an open/high resistance.

6. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 5 and ground.

瀚慖f the test lamp does not illuminate, test the ignition circuit for a short to ground or an open/high resistance.

7. Install a DMM between the actuator control circuit terminal 6 and ground. While monitoring the DMM, use the scan tool to command the

appropriate actuator from one direction to the other. The voltage on the control circuit should move from 0 volts in one direction to 5 volts in

the other direction and 2.5 volts in the at rest state.

瀚慖f the voltage does not change, test the control circuit for an open, short to voltage or short to ground. If circuit tests normal replace the

HVAC control module.

8. If all circuits test normal, replace the actuator.
