Test Procedure

WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Use the Flex Probe Kit for all test connections to prevent damage to the wiring terminals. Do not use standard multimeter probes.

N1 - CHECK FOR DTCs
- Connect the diagnostic tool.
- Retrieve and document continuous DTCs.
- Are any DTCs retrieved?
  1. Yes : go to ANTI-LOCK BRAKE SYSTEM (ABS)/TRACTION CONTROL AND ABS/TRACTION CONTROL WITH ADVANCE TRAC®/IVD DIAGNOSTIC TROUBLE CODE (DTC) INDEX .
  2. No : GO to N2.

N2 - CHECK THE ADVANCE TRAC®/IVD SWITCH
- Disconnect: Advance Trac®/IVD Switch C3208.
- Key in OFF position.
- Press the Advance Trac®/IVD switch to the ON position.
