Circuit/System Testing
1. Ignition OFF, disconnect the X1 (LF1) or X2 (LAU) harness connector at the K20 ECM.
2. Connect a test lamp between the appropriate signal circuit terminal listed below and ground.
* Terminal 57 (LF1)
* Terminal 52 (LAU)
3. Ignition ON, verify the test lamp turns ON and OFF when pressing and releasing the brake pedal.
瀚慖f the test lamp is always ON, test the signal circuit for a short to voltage. If the circuit tests normal, replace the K9 BCM.
瀚慖f the test lamp is always OFF, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace
the K9 BCM.
4. If all circuits test normal, replace the K20 ECM.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.

DTC Descriptor
DTC P0575
- Cruise Control Switch Signal Circuit
Circuit/System Description
When a cruise control function switch is activated, the body control module (BCM) detects a predetermined voltage. The BCM sends a serial data
message to the engine control module (ECM) indicating the function that has been requested.
