DTC P1436: Regeneration Request Failures Malfunction

CAUTION
!
• The parameters must be reinitialised after any procedure is carried out on the diesel particulate
filter.
Use command "Initialize Diesel PF data" on SUZUKI scan tool, and diesel particulate filter after-
sales regeneration referring to "Diesel Particulate Filter After-sales Regeneration Procedure: in
Section 1C" or "Diesel Particulate Filter Removal and Installation: in Section 1K".
• In order to enable the diesel particulate filter to self-clean automatically, we recommend that you
drive as soon as possible for up to about 20 minutes after diesel particulate filter warning light
turning ON, at an average speed of 75 km/h (46 mph) compatible with:
– The road conditions.
– Respect for authorised speed limits.
NOTE
• Conditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
• If the fault is present:
– Diesel particulate filter warning light is lit.
– Specific driving requirement to regenerate the diesel particulate filter when driving.
• Order of priority in the event of more than one fault:
– Firstly, deal with fault "DTC P1431: Clogged Particulate Filter Failures Malfunction: " if it is
present or stored.
Troubleshooting
• Fault appears following several failed regeneration attempts when driving, or if the weight of soot in the filter is
above 50 g.
• Do not start diesel particulate filter after-sales regeneration with SUZUKI scan tool.
Regeneration must absolutely be carried out when driving insofar as possible.
The diesel particulate filter warning light is displayed on the combination meter to show a risk of the filter
becoming saturated.
