ISSUE:

The Anti-Lock Brake System (ABS) Malfunction Indicator Lamp (MIL) may illuminate on some vehicles. Diagnostic Trouble Codes (DTCs) C1145, C1148, C1155, C1158, C1233, and C1234 may be stored in memory. This may be caused by a short due to water intrusion in the right or left front ABS wheel sensor harness connection(s).

ACTION:

Refer to the following Service Procedure to determine if DTCs are the result of water intrusion into the ABS sensor harness connection(s).

SERVICE PROCEDURE

  1. Is there an ABS code in memory (using the New Generation Star (NGS) tester to list the codes)?
    • If YES, proceed to Step 2.
    • If NO, this TSB article is not applicable. Proceed with normal diagnostics in the 1997 F-Series Service Manual.
  2. Is one or more of the ABS DTCs C1145, C1148, C1155, C1158, C1233, C1234 present in memory?
    • If YES, proceed to Step 3.
    • If NO, this TSB article is not applicable. Proceed with normal diagnostics in the 1997 F-Series Service Manual.
  3. Measure the resistance between the two (2) ABS wheel sensor terminals at the sensor harness connector. Is the ABS wheel sensor resistance between 2000 and 4000 ohms.
    • If YES, proceed to Step 4.
    • If NO, replace both front ABS Wheel Sensors (-2C204-) and clear DTCs.
  4. Measure the resistance between the sensor terminals at the sensor harness connector and chassis ground. Is anything, but open circuit, indicated?
    • If YES, replace both front ABS Wheel Sensors (-2C204-) and clear DTCs.
    • If NO, proceed to Step 5.
  5. Is the vehicle build date between 11/30/95 and 2/27/96?
    • If YES, replace both front ABS Wheel Sensors (-2C204-) and clear DTCs.
