Displaying & Reading Trouble Codes

CAUTION: Care must be taken to connect only the (BK/OG) stripe wire to ground. Connecting the mating connector wire to ground will result in a blown fuse.

Note: The ignition switch must be in the RUN position (engine does not need to be running), before disconnecting the RAB II diagnostic connector or the diagnostic trouble codes (DTCs) will be erased. Next, locate the black RABS II diagnostic connector. The diagnostic C244 has two mating halves, one of which has a (BK/OG) wire. Disconnect the diagnostic connector C244.

Attach one end of a jumper wire with a 10A in-line fuse to the (BK/OG) wire side of the diagnostic connector C244. Ground the opposite end of the jumper wire until the ABS light begins to flash. Grounding the (BK/OG) wire starts the yellow ABS warning indicator flashing. If grounding the (BK/OG) wire does not start the yellow ABS warning indicator flashing, refer to Symptom Chart.Symptom Related Diagnostic Procedures

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 DTC 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 DTC 16 is obtained when the anti-lock brake control module detects normal system operation.
