ISOCheck Re Launch & New User Guide
The
ISO tester is an advanced circuit tester, it tests a trucks ISO 7638 socket, trailer susie and ABS/EBS functions.
With the launch now well under way, we can detail here the latest user guide.
When using the ISOCheck on a tractor and trailer, please make sure all health & Safety procedures are in place.
The ISOCheck is a test product & a diagnostic tool, the test lead will quickly identify where the fault is .i.e. on a tractor unit, a trailer or the existing Susie lead.
Testing a Tractor Unit
Firstly make sure the ignition is off in the tractor unit, remove the existing Susie lead that is fitted into the ISO socket.
Apply the ISOCheck to the ISO7638 socket on the tractor unit, fit the end with the clear Perspex modification, for future reference this is called “the ISOIndicator”.
Turn on the ignition, with all voltages and earths correct and also the ABS warning light “off” the ISOIndicator will light up GREEN.
If any of the voltages, earths or the warning light circuit is faulty, then the ISOIndicator will light up RED (or warning light on), this indicates a fault with the tractor unit, with the EBSPlus version the lead will now go into diagnostic mode and flash a count sequence in relation to the pin that is at fault. i.e. 5 flashes indicates PIN 5 “the warning light control wire”.
If the
ISOCheck Truck Test resulted in Green and to confirm the trailer has a fault, not follow the trailer test procedure.
Testing the Trailer
Turn the truck ignition off.
Plug the ISOCheck Indicator into the trailer, turn on the ignition. The trailer warning light should activate on the truck dash board and the ISOCheck will light up RED.
The warning light should go out after 2 seconds and the ISOCheck will go GREEN, this means the trailers braking system is working at standstill.
If the warning light stays on, then drive the tractor and trailer above 10KPH, the warning light should go out and the ISOCheck will go GREEN. This proves the braking system is working correctly.
If all is working correctly and there is still an ABS fault light, this would mean the existing Susie lead is probably faulty. If the tester stays RED after a drive, stop the unit and trailer and remove the ISOCheck from the trailer. If the tester stays RED there is a power supply fault from the tractor unit or warning light fault, if the ISOCheck Indicator goes GREEN then there is a fault in the trailer system.
