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.
Switch the ignition to ON.
Retrieve any DTCs.
Are any DTCs displayed?
|
Yes
|
DTC P242F:00, P252F:00, P253F:00, P2458:00 or P2463:00 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 main relay and PCM terminal 119 or 120
• Open circuit main relay and PCM terminal 105
• Main relay stuck open
• Open or poor ground circuit (PCM terminal 1, 2, 3, 114 or 117)
• Poor connection to vehicle body ground

|
Yes
|
Replace the specified engine oil.
Perform the engine oil initialize procedure.
|
|
No
|
Go to the next step.

|
Monitor the PM_ACC, PM_GEN and PM_ACC_DSD PIDs using the M-MDS.
Are monitored values 8 g/L {0.50 lb/ft3} or less?
|
Yes
|
Go to Step 10.
|
|
No
|
If each PIDs value are 11 g/L {0.69 lb/ft3} or less;
Go to the next step.
If each PIDs value are above 11 g/L {0.69 lb/ft3};
Go to Step 5.

Yes
|
Go to DTC P2428:00 diagnostic procedure.
|
|
No
|
Go to Step 10.
|

|
5
|
Monitor the PM_ACC, PM_GEN and PM_ACC_DSD PIDs using the M-MDS.
Is one of the PID monitored value 15 g/L {0.94 lb/ft3} or less?
|
Yes
|
Go to the next step.
|
|
No
|
Replace the oxidation catalytic converter, then go to Step 11.
|
||
|
6
|

|
Yes
|
Go to DTC P2428:00 diagnostic procedure.
|
|
No
|
Go to the next step.
|
||
|
10
|

Does diesel particulate filter assessment procedure operate properly?
|
Yes
|
Go to the next step.
|
|
No
|
Reinspect from Step 1.
|
||
|
11
|
Clear the DTC from PCM memory.
Verify the diesel particulate filter lamp condition.
Does the diesel particulate filter lamp illuminate?
|
Yes
|
Go to Step 1.
|
|
No
|
Troubleshooting completed, go to the next step.
