Antilock Brakes / Traction Control Systems: Testing and Inspection Procedures Diagnostic Trouble Code Retrieval NOTE: Ford DOES NOT provide procedures other than those described to retrieve or clear trouble codes.

NOTE: Verify the ignition switch (11572) is in the RUN position (engine does not need to be running). Next, locate the black RABS II diagnostic connector. The diagnostic connector has two mating halves (one of which has a black/orange wire connected to it). Disconnect the two halves.

NOTE: Some Aerostar vehicles were built with locking terminals in the diagnostic connector, making it difficult to disconnect the two mating halves.

Use the following procedure Steps 1 through 4 if servicing an Aerostar with locking terminals. 1. Lift the latch on the female housing to disengage the locking mechanism. 2. Attempt to separate the two connector halves until the terminals lock. 3. On the top portion of the connector housing, opposite the mounting tabs, there is a small hole. Insert a narrow blade screwdriver or scribe type tool into the hole until it stops. 4. Separate the two connector housing halves by pushing the tool handle toward the black/orange wire. CAUTION: Care must be taken to connect only the black/orange stripe wire to ground. Connecting the mating connector wire to ground will result in a blown fuse. 5. Attach one end of a jumper wire to the black with orange stripe wire side of the diagnostic connector. 6. Momentarily ground the opposite end of the jumper wire by connecting it to a good chassis ground for 1-2 seconds.

Grounding this wire should start the REAR ABS lamp flashing. If grounding this wire does not start the REAR ABS lamp flashing, go to System Pre-Check Test D , Yellow REAR ABS Light Self-Check OK, but No Diagnostic Trouble Code When Diagnostics started. See: Description of On-Board Diagnostics/System Self-Check/System Self-Check Pinpoint Tests/D - Yellow RABS light OK/ No Self Check

The code consists of a number of short flashes and ends with a long flash. Count the short flashes and include the following long flash in the count to obtain the code number. For example, three short flashes followed by one long flash indicates diagnostic trouble Code 4. The code will continue to repeat itself until the key is turned off. It is recommended that the code be verified by reading it several times. This code will be used later for system repair instructions, it should be written down for future use. A diagnostic trouble code of 16 will be obtained when the module detects normal system operation. For any other codes refer to the Code chart for a description of any other codes.

Antilock Brakes / Traction Control Systems: Testing and Inspection Procedures Trouble Code Descriptions CAUTION: When checking resistance in the RABS II system, always disconnect the battery ground cable. Improper resistance readings may occur with the vehicle battery connected. NOTE: Refer to Obtaining the Diagnostic Trouble Code in this section for procedure to obtain flashout code. See: Displaying & Reading Trouble Codes/Diagnostic Trouble Code Retrieval

For easier access to the RABS II valve connector, construct a jumper harness with a 4-pin connector F07Z-14A464-B and four sections of 18-inch long wire. The wire sections should be of different colors or labeled for quick reference.
