DIESEL PARTICULATE FILTER LAMP FLASHES |
|---|---|
|
DESCRIPTION
|
• Diesel particulate filter lamp flashes because the diesel particulate filter system can not dispose of diesel particulate
|
|
POSSIBLE CAUSE
|
• Driving condition is not in diesel particulate filter regeneration condition
• Diesel particulate filter is not regenerated by manual regeneration procedure
• Diesel particulate filter damaged or deterioration
• Erratic signal input to PCM
• PCM does not realize the diesel particulate trap amount in diesel particulate filter
|
Diagnostic Procedure
|
STEP |
INSPECTION |
RESULTS |
ACTION |
|---|---|---|---|
|
1
|
Connect the M-MDS to the DLC-2.
Turn the engine switch to the ON position.

|
Yes
|
DTC P242F, P252F, P253F or P2458 is displayed:
Go to the next Step.
Other DTC is displayed:
Go to the appropriate DTC test.
Communication error message is displayed:
Inspect the following:
• Open circuit between PCM control relay and PCM terminal 119 or 120
• Open circuit PCM control relay and PCM terminal 105
• PCM control relay stuck open
• Open or poor ground circuit (PCM terminal 1, 2, 3, 114 or 117)
• Poor connection to vehicle body ground

Is one of the PID monitored value 15 g/L or less?
|
Yes
|
Go to the next step.
|
|
No
|
Replace the diesel particulate filter, then go to Step 10.
|
||
|
6
|

|
Go to the next step.
|
|
11
|
Retrieve any DTCs.
Is DTC P2428 detected?
|
Yes
|
Go to DTC P2428 diagnostic procedure.
|
|
No
|
Go to the next step.
|
||
|
12
|

Does diesel particulate filter assessment procedure operate properly?
|
Yes
|
Go to the next step.
|
|
No
|
Reinspect from Step 1.
|
||
|
13
|
Clear the DTC from PCM memory.
