If scan tool communicates with EBCM, go to next step. If scan tool does not communicate with EBCM, go to TEST C: SCAN TOOL DOES NOT COMMUNICATE WITH ELECTRONIC BRAKE CONTROL MODULE under SYSTEM TESTS.
- Using scan tool, attempt communication with non ABS systems. If scan tool does not communicate with non ABS systems, go to TEST B: SCAN TOOL DOES NOT COMMUNICATE WITH UNIVERSAL ASYNCHRONOUS RECEIVE & TRANSMIT DATA LINE under SYSTEM TESTS.
