MSB No. 010 Fires on light 4wd vehicles

Information:

Within a two month period two underground fires on Toyota 4 x 4 Land Cruisers were reported. In each case the fire was caused by the engine being driven backwards, as the vehicle rolled back after stalling on an incline, while still in forward gear. This caused the airfilter to ignite due to the combustion cycle being reversed.

Both vehicles were HJ75’s with 2H engines. The 2H series engines are originally supplied with Electronic Diesel Injection Control (EDIC) motors that prevent the combustion cycle being reversed. In both the reported incidents the vehicle EDIC had been removed.
