Diagnostic Tests: Notes

NOTE: When using self-diagnostic tests, DO NOT skip any test steps unless instructed to do so, or incorrect diagnosis may result. For connector terminal identification, see CONNECTOR IDENTIFICATION under DIAGNOSIS & TESTING. To identify circuits and wire colors referenced in testing, see WIRING DIAGRAMS .

NOTE: Self-diagnostic tests are written specifically for Diagnostic Readout Box (DRB-III). A generic scan tool may not be capable of performing all necessary test functions. After repair is made, perform ABS VERIFICATION TEST under DIAGNOSTIC PROCEDURES to verify proper system operation.
