IMPORTANT: BOB cable assemblies have not been produced for ABS 5.3, ABS 5.4 or TC/ABS 5.3. Unless otherwise stated, the test readings are those that should be obtained on the control module's connector (unplugged). For TC/ABS 5.3, certain readings can be taken with the BOB cable assembly connected to the Trionic T7 control module, see the notes under Test reading.

= greater than; < = less than; ~ = alternating current (LP: LOGIC PROBE P = select pulse; p = visible pulse)
