4. Connect the X2 harness connector at the K8 keyless entry control module. Disconnect the X3 harness connector at the K 9 BCM.



5. Ignition OFF, test for less than 1 V between the ignition circuit terminal 5 and ground.



瀚慖f greater than the specified range, test the ignition circuit for a short to voltage. If the circuit tests normal, replace the K84 keyless entry



control module.



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. If the circuit tests normal,



replace the K84 keyless entry control module.



7. If all circuits test normal, replace the K9 body control module.

Diagnostic Instructions



* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System



Check - Vehicle) prior to using this diagnostic procedure.



* Review Strategy Based Diagnosis (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Strategy Based Diagnosis) for an



overview of the diagnostic approach.

DTC Descriptor



DTC B1474 02



- Passenger Exterior Door Handle Switch Circuit Short to Ground



Diagnostic Fault Information



Circuit/System Description



The keyless entry control module supplies a 12V signal to the passenger exterior door handle switch. When the door handle is activated, the switch



closes and the voltage signal from the keyless entry control module is pulled to ground, this input allows the keyless entry control module to detect



a door open request



Conditions for Running the DTC



Battery voltage is between 9-16 V.



Conditions for Setting the DTC



The keyless entry control module detects the right front exterior door handle switch signal circuit is shorted to ground or closed for greater than 60



s.



Action Taken When the DTC Sets



Passenger door will not open unless the passenger door is unlocked.



Conditions for Clearing the DTC



* The DTC will be current for as long as the fault is present.



* When the fault is no longer present, the DTC will be a history DTC.

2010 Cadillac Truck SRX AWD V6-3.0L Page 1292 The engine control module (ECM) supplies voltage to each fuel injector on the injector high voltage supply circuits. The ECM energizes each fuel injector by grounding the high voltage control circuit of the fuel injector. The ECM monitors the status of the injector high voltage supply circuits and the fuel injector high voltage control circuits. When a fuel injector circuit condition is detected by the ECM, the affected fuel injector(s) is disabled. Conditions for Running the DTC * The engine is running. * The ignition voltage is between 11-18 V. * The DTCs run continuously when the above conditions are met. Conditions for Setting the DTC P2147, P2150, P2153, P2156, P216B, or P216E The ECM detects the injector high voltage supply circuit is shorted to ground for greater than 2 s.
