What does no powertrain DTC's or freeze frame data mean?

#4 · Apr 13, 2013. "No Powertrain DTC's or Freeze Frame Data is presently stored in vehicles computer" No powertrain DTC - No diagnostic trouble codes - e.g. no problems. No freeze frame data - data which is stored when a problem is recognized. e.g. no problems - no data.

What is a freeze frame code?

When the engine computer (PCM) detects a fault and turns the Check Engine light on, it also stores a freeze frame related to that fault. A freeze frame is snapshot of data from a number of sensors and components at the time when the fault was detected.

How do you interpret freeze frame data?

OBDII Freeze Frame Data And Their Meaning:

  1. P0420 error occurs twice a month, and it means readiness codes are reading well.
  2. Fuel SYS 1 CL means the fuel injection bank is in closed-loop mode.
  3. Fuel SYS 2 N/A means there is no fuel injector in bank 2. ...
  4. Load PCT 92.2 indicates that the air entering the engine is below 100%.

Why would you view freeze frame data?

1 What is Freeze Frame Data? In simple words, whenever the computer detects a fault and illuminates the CEL, it also clicks and stores freeze frame data related to the issue. This data is essentially a snapshot from a number of components and sensors. You can view this information to find the cause of the problem.

How does freeze frame work?

In film and video, a freeze frame is when a single of content shows repeatedly on the screen—"freezing" the action. This can be done in the content itself, by printing (on film) or recording (on video) multiple copies of the same source frame. This produces a static shot that resembles a still photograph.

What is a freeze frame Drama?

stimulate the next part of the drama. Freeze-frame. A freeze-frame is a form of still image that is achieved by simply freezing action. Pedantically speaking, it provides a still image that is not pre-planned and can be likened to pressing a pause button to halt a film clip.

How can I remove DTC permanently?

A Permanent Diagnostic Trouble Code (DTC) is stored when a DTC is confirmed and the Malfunction Indicator Lamp (MIL) has been illuminated. A Permanent DTC can only then be cleared by the module strategy and cannot be erased by clearing DTCs with a scan tool, a Keep-Alive Memory (KAM) reset, or battery disconnect.

What is a freeze frame quizlet?

What is freeze frame? A shot that has so many frames that repeat, that it appears to not be moving.

How do you interpret OBD2 data?

In normal cases, the STFT data reading should shift rapidly between rich and lean. The LTFT should indicate a more stable percentage.
...
No matter the case, the first live data you should read upon connecting the OBD2 scan tool is the STFT and LTFT.

  1. During engine idle.
  2. At 1,500 rpm; and.
  3. At 2,500 rpm.

What does load PCT mean?

LOAD_PCT are: Reaches 1.0 at WOT at any altitude, temperature or rpm for. both naturally aspirated and boosted engines. Indicates percent of peak available torque. Linearly correlated with engine vacuum. Often used to schedule power enrichment.

What is EGR error percentage?

The EGR Error is also normalized for all types of EGR systems. The reading is based on a simple formula: (Actual EGR Position − Commanded EGR) ÷ Commanded EGR = EGR Error. For example, if the EGR valve is commanded open 10% and the EGR valve moves only 5% (5% − 10%) ÷ 10% = −50% error.

What means DTC?

DTC stands for Diagnostic Trouble Codes. A DTC code is a series of diagnostic trouble codes used by a vehicle's onboard diagnostics (OBD) system to alert you when a vehicle experiences a malfunction. Different DTC codes represent specific problems in your vehicle.
