Circuit/System Verification
1. Engine running, accessories OFF, measure and record the battery voltage at the 12 V battery terminals. The voltage should be between
12.6-15.0 V.
瀚慖f not within the specified range, refer to Charging System Test (See: Starting and Charging/Testing and Inspection/Component Tests
and General Diagnostics/Charging System Test).
2. Observe the scan tool EBCM Battery Voltage Signal parameter. The reading should be between 12.6-15.0 Volts.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the EBCM.
2. Ignition OFF and scan tool disconnected, open and close the driver door, and wait 1 minute. Test for less than 5 Ohms between the ground
circuit terminal 38 and ground.
瀚慖f greater than the specified range, test the ground circuit for an open/high resistance.
3. Verify that a test lamp illuminates between the 12 V B+ circuit terminal 25 and ground.
瀚慖f the test lamp does not illuminate, test the 12 V B+ circuit for a short to ground or an open/high resistance.
4. Ignition ON, verify that a test lamp illuminates between the ignition circuit terminal 14 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.
5. If all circuits test normal, replace the EBCM.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

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 10 ohms 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 greater than 250 counts.
瀚慖f greater than the specified range, test the signal circuit terminal 9 for a short to ground.
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 less than 4 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.
