ISSUE
Some 2004-2005 Freestar and Monterey vehicles may exhibit a traction control indicator on, anti-lock brake system (ABS) indicator on, and/or self ABS activation with a diagnostic trouble code (DTC) C1288.
ACTION
It may be necessary to replace the ABS module the hydraulic control unit (HCU), or the brake pressure switch. Refer to the following Service Procedure.
SERVICE PROCEDURE
NOTE
IF THE DTC C1288 IS PRESENT ALONG WITH OTHER DTCS, REPAIR THE OTHER CODES FIRST BEFORE CONTINUING WITH THIS TSB.
1. First perform normal diagnostics per Workshop Manual, Section (WSM) 206-09.
a. If the concern is corrected, return the vehicle to the customer.
b. If the concern is still present, proceed to Step 2.
2. Ensure that the latest ABS module is installed.
a. If the prefix starts with "4" (4F23 or 4F2Z) proceed to Step 3.
b. If the prefix starts with "5" or "6" proceed to Step 4.
3. Install latest level ABS module. When installing, check for water on the circuit board and/or in the aluminum cavity of the HCU. If water is present, replace the HCU as well. Refer to WSMI, Section 206-09 for removal and installation procedures. Perform IVD calibration sequence.
a. If the concern is corrected, return the vehicle to the customer.
b. If the concern is still present and only the ABS module was replaced, proceed to Step 4.
c. If the concern is still present and both the ABS and HCU were replaced, proceed to Step 5.
4. Monitor the brake pressure transducer (MPRETDR) PID using IDS. The KOER PID reading should be fluctuating with no brake pedal applied, this is normal. Lightly apply the brake pedal and the PID reading should increase with brake pedal pressure and decrease as you release the brake pedal.
a. If the brake pressure transducer does not operate as described, replace the HCU assembly. If the concern is corrected, return the vehicle to the customer.
b. If the brake pressure transducer does operate as described, or if concern is still present after HCU replacement, proceed to Step 5.
5. Replace the brake pressure switch (BPS) at the master cylinder.
NOTE
FOR AN INTERMITTENT C1288, MONITOR (MPRETDR) PID DATA WHEN THE CODE SETS, LOOK FOR INTERFERENCE FROM ELECTRIC MOTORS (SUCH AS WINDSHIELD WIPERS OR POWER SEATS). REPLACE THE ABS MODULE FOR THIS CONDITION.
