Points to remember

  1. Observe the test conditions. Use common sense in assessing the readings.
  2. The test readings presented are taken with the ignition switched ON unless otherwise stated.
  3. Start by checking that the control module is receiving power and is grounded.
  4. Check all sensor inputs and signals from other systems.
  5. Finally, check the control module outputs. Remember that the readings do not provide an indication that the actuator is operating.
  6. If any reading is not OK, consult the wiring diagram to trace the leads, connectors or components that need further checking.
  7. The specified readings are valid for a correctly calibrated Fluke 88/97.
  8. 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+).

IMPORTANTBOB 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 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)
