TC/ABS 5.3
TC/ABS 5.3
Scope
Values and readings for measuring signals and levels in the TC/ABS control module are given in the following pages.
^ Observe the test conditions. Use common sense in assessing the readings.
^ The test readings presented are with the ignition switched ON unless otherwise stated.
^ Start by checking that the control module is receiving power and is grounded.
^ Check all sensor inputs and signals from other systems.
^ Finally, check the control module outputs. Remember that the readings do not provide an indication that the actuator is operating.
^ If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components that need further checking.
^ The specified readings are valid for a correctly calibrated Fluke 88/97.
^ The readings %(+) and ms(+) indicate the pulse ratio and pulse length. A test instrument capable of measuring both pulse ratio and pulse length must be used. The "+" sign denotes a positive trigger pulse (TRIG+).
Connection, test readings
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 column in the tables.
