2010 Cadillac Truck SRX FWD V6-3.0L Page 946

1. Ignition ON, observe the DTC information with a scan tool. DTC P0641, P0651, P0697, or P06A3 should not set.

2. Observe the appropriate scan tool 5 V Reference Circuit Test Status parameter. The parameter should display OK or Not Run.

3. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the

conditions that you observed from the Freeze Frame/Failure Records data.

Circuit/System Testing

Note: Additional DTCs will set when disconnecting the components.

1. Ignition OFF, disconnect the harness connector of all appropriate sensors for the applicable DTC. Refer to Diagnostic Aids.

2. Ignition ON, test for 4.8-5.2 V between each of the affected 5 V reference circuits and ground.

瀚慖f the voltage is less than the specified range, test for a short to ground or for an open between the ECM and the affected circuit splice. If

the circuit tests normal, replace the K20 ECM.

瀚慖f the voltage is greater than the specified range, test for a short to voltage on the 5 V reference circuit. If the circuit tests normal, replace

the K20 ECM.

Note: A short to voltage on the signal circuit of certain components may cause this DTC to set.

3. Connect each component associated with the affected 5 V reference circuit one at a time while monitoring the appropriate scan tool 5 V

Reference Circuit Status parameter. The parameter should continue to display OK.

瀚慖f the parameter displays Fault when a component is connected, test the signal circuit of that component for a short to voltage. If the

circuit tests normal, replace the component.

瀚慖f greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K20

ECM.

3. Ignition ON, test for 4.8-5.2 V between the 5 V reference circuit terminal 1 and ground.

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

replace the K20 ECM.

瀚慖f greater than the specified range, test the 5 V reference circuit for a short to voltage. If the circuit tests normal, replace the K20 ECM.

4. Verify the scan tool BARO Sensor parameter is less than 1 kPa (0.2 psi).

瀚慖f greater than the specified range, test the signal circuit terminal 3 for a short to voltage. If the circuit tests normal, replace the K20 ECM.

5. Install a 3 A fused jumper wire between the signal circuit terminal 3 and the 5 V reference circuit terminal 1. Verify the scan tool BARO

Sensor parameter is greater than 127 kPa (18.4 psi).

瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace

the K20 ECM.

6. If the circuits test normal, replace the B17 BARO sensor.
