Circuit/System Testing
1. Ignition OFF, disconnect the harness connector of the ESC module.
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 47 and ground.
锟斤拷If greater than the specified range, test the ground circuit for an open/high resistance.
3. Verify that a test lamp illuminates between the 12V B+ circuit terminal 32 of the ESC module and ground.
锟斤拷If the test lamp does not illuminate, test the 12V B+ circuit for a short to ground or an open/high resistance.
4. If all circuits test normal, replace the ESC module.
Repair Instructions
Perform the Diagnostic Repair Verification (See: Verification Tests) after completing the diagnostic procedure.
Control Module References (See: Testing and Inspection/Programming and Relearning) for ESC module replacement, setup and programming.
