ABS 5.4

Test readings, control module connections
Scope
The following pages include the values and readings for measuring the signals and levels in the ABS control module.


Points to remember:





^ Observe the test conditions. Use common sense in assessing the readings.
^ 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 rat and pulse length must be used. The 'Y' sign denotes a positive trigger pulse (TRIG+).

IMPORTANT: Unless otherwise stated, the test readings are those that should be obtained on the control module connector (unplugged).
