Pinout Values and Diagnostic Parameters
The symptom charts (in addition to providing diagnosis by symptoms) will also cross reference the diagnostic trouble codes to the appropriate pinpoint test.
NOTE: Use Rotunda 88 Digital Multimeter 105-00053 or equivalent to perform electrical pinpoint tests.
There are times when a customer concern will not cause the yellow REAR ABS warning light to illuminate or a code to be stored.
The symptom chart is intended to give the technician a starting point in resolving these types of concerns. The chart also describes conditions that will illuminate the yellow RABS light.
Please note that both the red BRAKE warning light diagnosis procedure and test drive are required prior to performing the tests in this section. Failure to perform these procedures will greatly diminish the effectiveness of this method of diagnosis.
