<Short wheelbase>

caution

When the catalytic converter or DPF is replaced, use the M.U.T.-III to initialise the learning value (Refer to GROUP 00 - Precautions Before Service, Initialisation Procedure for Learning Value in DPF System .)
When the catalytic converter is replaced, perform the forcible DPF regeneration after learning value in DPF system (Refer to GROUP 17 - Diesel Particulate Filter (DPF) System, Forcible DPF Regeneration .)
When the No.1, No.2 or No.3 exhaust gas temperature sensor is replaced, perform the forcible DPF regeneration (Refer to GROUP 17 - Diesel Particulate Filter (DPF) System, Forcible DPF Regeneration .)
