4.3.5 Special Functions
Special tests are bi-directional diagnostic tests on anti-lock brake systems and air bags. The tests
let you to use the scanner temporarily activate or control a vehicle system or component, and
when you exit the test, the system/component returns to normal operation.
Some tests display a command to the operator. For example, if “Press Brake Pedal” displays, the
operator has to press and hold the brake pedal and then continue. The number, and type of tests
will vary for each vehicle, year and components.
Typical special test options include:
●
ABS Manual Control Tests
– allows to manually control the actuators in order to test ABS
motors, solenoids, solenoid enable relays, EMBs, and more.
●
ABS Motor Test
– allows to manually control the ABS pump motor.
●
ABS Version Test
– displays the name of the brake system and the ABS controller version
number, software ID, and sequence value.
●
Actuator Tests
– allows to manually control the actuators in order to test AYC valves, inlet
valves, outlet valves, pump motors, and TRACS valves.
●
Autobleed Test, Automated Bleed, or Service Bleed
– removes air from the internal brake
fluid chambers after servicing the brakes.
IMPORTANT
●
Before bleeding the brake system, make sure no diagnostic codes are present.
●
Do not let the master cylinder run dry during the brake bleeding procedure.
●
Do not allow brake fluid to contact the motor pack or the electrical connectors.
●
Use a recommended brake fluid. Do not use silicone brake fluids in an ABS-equipped vehicle.
After bleeding the brake system, check the brake pedal for excessive travel or a “spongy” feel.
Bleed again if either condition is present.
●
Automated Test
– automatically commands each solenoid valve and the pump motor on and
off to test for proper operation.
●
Brake Bleed Preparation Test
– prepares the brake lines for bleeding by clearing air from the
modulator. The test rehomes all the ABS and TCS motors, cycles the TCS motors, and then
returns all motors to the “home” position at the bottom of the bore.
●
Function Test
– automatically commands the ABS relay, valve solenoids, and pump motor on
and off to test for proper operation.
●
Gear Tension Relief Test
– relieves tension from the ABS motor gears so you can separate
the ABS motor pack from the ABS hydraulic modulator.
●
Hydraulic Control Tests
– allows to manually engage and disengage the ABS solenoids for
troubleshooting the hydraulic functions.
●
Idle Up Manual Control Test
– allows to manually control the idle up actuators.
●
Lamp Tests
– allows to manually control the ABS or TCS warning or indicator lamps.
●
Motor Rehome Test
– prepares the brake lines for bleeding by clearing air from the
modulator. The test returns all ABS motors to their “home” positions.
●
Pump Motor Tests
– allows to manually control the pump motor.
●
Relay Test
– allows to manually engage and disengage either the ABS or TCS relays in order
to test relay operation.
●
Requested Torque Test
– allows to manually control the engine torque to test for proper
operation of the traction control system (TCS).
●
Setup SDM Serial Number (Air Bag Sensing and Diagnostic Module)
– allows to program
a new air bag serial number into the dash integration module (DIM). You use this test after
installing a new air bag; otherwise a diagnostic trouble code will be set when you turn on the
ignition.
●
Solenoid Tests
– allows to manually control the inlet and output valve solenoids.
