For the JCB machines: cold start control unit 728/26800, an aftermarket part.

According to sources, 728/26800 is the cold start ECU used on JCB backhoe loaders and telehandlers; the product card lists it as the heater control unit. Depending on engine temperature, it decides how long the cold-start aid (grid heater or glow plugs) runs and tells the operator when pre-heating is complete. A faulty unit causes hard cold starts, white smoke or a heater that stays on and drains the battery. Before replacing it, check the heater relay, temperature sensor and fuse.

Fitting

Before replacing the control unit, switch off the ignition and disconnect the battery negative, then unplug the connectors by pressing their latches. After fitting the new unit, if the machine's software and settings require it, program or configure the unit with the JCB diagnostic tool (ServiceMaster). Push the connectors fully home without bending any pins and test every function. The part comes new; before fitting, compare its part number and connection type with the old part. After the change, check the function and the warnings on the instrument panel.
