NOTES ON THE USE OF THIS MANUAL

Preceding the Modular main indexsheet, this manual should containthe document registration formand an amendment record sheet.Both of these documents areintended to assist your Companyand Haldex Brake Products Ltd inmaintaining this manual in an upto date condition.Please follow the instructionsincluded on each sheet to ensurethat we are able to give bothyourself and your company thebest product information supportwhenever the need may arise.

For ease of reference each sectionof this manual deals with theindividual systems of MODULARtrailer ABS .

This manual has been designed toassist personnel in satisfactorilyinstallingMODULAR 1 UPGRADE,MODULAR 1 PLUS andMODULAR 2 ABSon semi-trailers.The intention has been to illustratethe various areas of installation. Itis expected that this manual willbe in possession of the appropriateperson throughout their 'training'and 'experience' and that themanual will be used as:

a) A teaching aid followingsupervision of a HALDEXENGINEER.

b) A reminder of the correctprocedure of MODULAR ABSinstallation.

For any other deviation consultHaldex Brake Products Ltd.Technical Services.

Use appropriate spare-partsdocumentation whenobtaining spare parts.

Use only genuine Haldexparts in repairs.

CHASSIS INSTALLATION - MODULAR 1 UPGRADE (2S/1M) shown for clarity

The preferred assembly orientation should bepositioned so that the ECU faces towards the rearof the semi-trailer.

Note:

This is particularly important on 2Msystems in order that the diagnostic codesfor modulators and sensor are correct.

POSITION OF MODULAR ASSEMBLYAssembly must be mounted vertically.

GROUND LEVEL

Care should be taken to provide reasonable excess tothe ECU for replacement of loom or ECU.

C = 200mm Minimum.D = 1. Assembly to be above axle centre line.

2. Adequate space should be provided for futurefitment of a exhaust silencer

While shrink sleeve is still warm, gently squeeze theend of the sleeve.

Make sure a amount of sealant is visible from the endof the sleeve. A watertight joint is formed when thesealant solidifies on cooling.

DO NOT over squeeze and create air gaps.

Before fully cooled, fold back sleeve on itself andsecure with a cable tie.

GENERAL CHASSIS COMPONENTSISO 7638 ConnectorShould be positioned / grouped with other electricalconnections.

When installing ISO 7638 it is important thatsufficient extra length of cable is allowed to exposethe socket assembly for replacement in service.

It will be necessary to pull the ISO 7638 socket clearor the trailer headboard to undo the gland nut.

Warning LampWhen wiring of warning lamp the cable outerinsulation must enter the rubber boot of the lamp.

FINAL PRODUCTION TEST PROCEDURE FOR 24V TRAILERINSTALLATIONS

Reference : GS 0105 (Issue 5) - Section 2

Scope

These tests verify that the wiring to the ABS electronic control unit (ECU) and piping to the ABS modulator has beensatisfactory completed.

Equipment Required

(Item 4 below is only required if the installation to be tested is not fitted with anInfo Centre)

1 A supply switch box with a 24 volt supply (see Figure 84).A smooth d.c. supply must be used. An a.c. supply will damage the ECU while a d.c.supply whose voltage varies by more than 4 volts, from the nominal 24V, willdegrade system performance.

2 A trolley jack and wheel chocks.3 Workshop compressed air supply (regulated to a maximum of 8 bar, minimum of 6

bar).4 A Diagnostic Display Unit (DDU) (Haldex part No. 905 027 001) and an ECU to DDU

2 metre cable assembly (Haldex part No. 003 8467 09).

Main Procedure

1 Lower any raised lift axles.

2 Connect and switch on the workshop compressed air supply to the trailer red and yellowlines.

3 Record the information requested below concerning the installation to be tested. Thisinformation may be obtained either from the installation drawing or by direct inspection ofthe trailer (preferred method).For all Modular installations. The location of each of the wheels to which a sensor isfitted.For Modular 1 Plus and Modular 2 installations only. Whether the installationincludes suspension control.For Modular 2 installations only. The physical position and connection to the brakechambers of each of the ABS modulators (BLUE and YELLOW) on the trailer, so thatin later testing the order in which they exhaust air can be identified.

4 Set all of the switches on the supply switch box to OFF and check that the ammeter linkhas been fitted.

5 If necessary locate the DDU output socket on the trailer and connect this socket to theDDU using the 2m cable assembly.

6 If the trailer is not fitted with or the ECU is not powered by an ISO1185 (24N) connector goto item 9.

i) The trailer mounted warning lamp will illuminate.

ii) On Modular 2 installations, a single short burst of air will beexhausted from each of the ABS modulators in the sequenceBLUE, YELLOW.

or On Modular 1 Upgrade or Plus installations, a single short burst of airwill be exhausted from the ABS modulator.

iii) The trailer mounted warning light will switch off for between 0.5 and 1second and then come on again permanently.

e) If necessary set the circuit breaker switch to OFF and repeat d) above to confirmvalve, lamp and DDU sequences.

8 If the trailer is not fitted with an ISO3731 (24S) connector go to item 11.

9 ISO3731 (24S) connector test

a) Set the circuit breaker switch and all other switches on the switch box to OFF andunplug the ISO1185 (24N) connector. Plug in the ISO3731 (24S) connector.

b) Set the warning light switch on the supply switch box to ON. Set the circuit breakerswitch on the supply switch box to ON. The lamp on the switch box will come onpermanently (wait for at least 2 seconds to check that lamp does not flash).Set the circuit breaker switch on the supply switch box to OFF. Note thatthe trailer mounted warning lamp will remain off throughout this ISO3731 test.

c) Set the ISO3731 B+P switch on the supply switch box to ON. If the ISO1185 (24N)connector test (point 7) was not required, carry out the Modular Configuration test asdescribed at the end of this procedure.


NOTE: If the trailers wired for 3 power option as drawing 911 304 001 the trailer warninglight will also come on during this test.

i) The supply switch box warning light will illuminate.

10 If the trailer is not fitted with an ISO 7638 connector go to item 12.

11 ISO7638 connector test

a) Set the circuit breaker switch and all other switches on the supply switch box to OFFand unplug the ISO3731 (24S) and/or the ISO1185 (24N) connector. Plug in theISO7638 connector. Note that the trailer mounted warning lamp will remain offthrougout this ISO7638 test.

b) Set the warning light switch on the supply switch box to ON. Set the circuit breakerswitch on the supply switch box to ON. The lamp on the switch box will come onpermanently (wait for at least 2 seconds to check lamp does not flash). Set the circuitbreaker switch on the supply box to OFF.

c) Set the ISO7638 B+P switch on the supply switch box to ON. If the ISO1185 (24N) andthe ISO3731 (24S) connector tests (point 7 and 9) were not required, carry out theModular Configuration test as described at the end of this procedure.


i) The supply switch box warning light will illuminate.

ii) On Modular 2 installations, a single short burst of air will beexhausted from each of the ABS modulators in the sequence BLUE, YELLOW.

CONFIGURATION TEST

1 Set the operating switch to ON and observe the DDU . The DDU will display 88 then a codein the range C0 - C2 for approximately 2 seconds followed by 07. If the installation includesoptional retarder and/or suspension control an additional A code or codes will appearbetween the C code and 07.

The group C code displayed is dependent on the number of modulators and sensors fitted tothe trailer (see main procedure item 3 - page 34).

C0 Modular 1 Upgarde and Modular 1 PlusC1 Modular 2 fitted with two wheel speed sensorsC2 Modular 2 fitted with four wheel speed sensors

The A codes for the optional additional control features are given below.A1 Manual raise/lower suspension control valveA2 Retarder control
