PowerTrak cylinder – 6680

Dismantling/assembling the ground pressure springs

T-codeValid

WARNING !

Note that the stated settings correspond to the lowest drive wheel pressure that allows standard safety for braking. Accordingly, under no circumstances may the initial pressure spring be adjusted so that the wheel pressure falls below the stated minimum value in table 1. However, if the stated setting gives insufficient grip for acceleration the drive wheel pressure can be adjusted upwards from the stated value without TOYOTA's product liability becoming invalid. Nevertheless, note that an excessively high drive wheel pressure can impair the truck's stability.

15.3.5 Sealing

When the spring has been adjusted to the correct position the system should be sealed. This is done by wrapping the wire (S29759) around the threaded sleeve both under and above the setting nut. The wire is then sealed by squeezing the plastic sleeve (S20421) with a pair of pliers.

16.1 General

TruckCom is a communication program which communicates with trucks equipped with CAN (Controller Area Network) communication. It enables the following tasks to be performed:

•downloading truck control software.

•viewing and adjusting operator / truck parameters and hour meters. Additionally, the truck’s parameter set (including hour meter values) can be saved to file and reloaded later.

•viewing diagnostic data for various digital inputs / outputs and analogue data including voltages, currents and certain temperatures.

The program is a Microsoft® Windows program running under Microsoft® Windows® 95/98, Microsoft® Windows® XP/2000 and Microsoft® Windows® NT.

16.2 Connection

A CAN interface of the CPC-PP type is needed to connect it to the truck, with attendant cable. Connect the interface via the printer port on a PC. Connect the cable between the interface and the truck's CAN terminal.

The CAN interface is supplied with power from the truck electronics and is protected from any high voltages in the truck if a fault should occur.
