PART 5: PRETESTING CHECKLIST

The pretesting checklist should always be completed prior to using the MUTT

UNIT PLACEMENT

• Place the tester on a ﬂ at, level surface.

• Chock trailer wheels to avoid rolling before testing brakes.

MAINTAIN CONNECTORS

Dielectric grease should be used on all connections to avoid corrosion. If a bad

connection exists at the terminal junction, you may get an erroneous reading and

the MUTT

will not work properly.

• Make sure you have a solid connection in the socket.

• Be certain the 7 pins in each plug are clean and spread to the proper size.

• Always check the MUTT

connector pins at the side of the MUTT

for proper

expansion. Over time, the pins may bend in slightly resulting in a poor connection

between the connector and the cable ends. A ﬂ at head screwdriver can be used

to expand the pins until a tight connection is made.

CABLE TESTING PROCEDURE

The MUTT

has a special cable feature to test 7-way round pin cables for continuity.

The cable testing feature can be used to test a tractor’s cable, or the supplied MUTT

cable. All cables should be tested prior to MUTT

operation.

• Insert each end of the cable into both side connectors on the MUTT

. Be sure to

push the cable ends in ﬁ rmly until they reach the bottom of the connector.

• Turn main power switch to a desired power supply.

• Once the power is selected, the green lights around the control knob will blink

and disappear one at a time until only the Ground Integrity Indicator remains solid

green. Once the initial check has been performed, poor cable conditions will be

shown by a blinking light for the problem circuit.

• If the cable has an open circuit or continuity problem, the corresponding circuit will

ﬂ ash repeatedly.

• Further testing can be performed by selecting each circuit individually via the

control knob or remote. When an open circuit is detected, the LED for the circuit

will ﬂ ash and an audible alert will be heard.

9.2 HALDEX BLINK CODES

To access Haldex Blink Codes, you must select the Brake Light Circuit and press the

control knob to cycle the Auxiliary Circuit the appropriate number of times using the

following directions:

See table below for modes and sequences:

1. Make sure trailer is stationary and wheels are properly chocked.

2. On the MUTT

, turn the control knob to select Brake Light Circuit.

3. Push the control knob to cycle Auxiliary Circuit ON for each desired ignition cycle.

Auxiliary Circuit will ﬂ ash.

5. Each Ignition Cycle must end with both Brake Light and Auxiliary Circuits

simultaneously powered. To do this, press and hold the control knob for ﬁ ve

seconds during the last ON cycle.

6. Count number of blinks on trailer ABS lamp, see following charts (pg. 28-32) for

speciﬁ c fault info.
