What does no power train DTC mean?
#4 ยท 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 Freeze Frame data?
In simple terms, a freeze frame is a snapshot of data. It’s a snapshot of sensor or component readings (parameter values) captured at the moment when the electronic control unit detected a malfunction. For example, when an engine misfire is detected, a snapshot of the current sensor values is captured.
How do I check my DTC code?
To read the codes, you will have to plug a scan tool or code reader into the 16-pin OBD II diagnostic connector, which is usually located under the dash near the steering column. The tool will then display the code or codes that have turned on the Check Engine Light. To read codes, you need the proper scan tool.
What does DTC 01 mean?
DTC 01 General Sensor Fault. DTC 02 Instantaneous Battery Voltage Out of Range. DTC 03 Filtered Battery Voltage Out of Range. DTC 10 Inside Air Temperature Sensor Voltage Low.
What are powertrain DTC codes?
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.
How do I check Freeze Frame data?
The freeze frame is stored in the PCM together with the diagnostic trouble code (DTC) related to the fault. If the freeze frame is available, it can be viewed with an OBDII scan tool. Mechanics at the dealerships use a manufacturer-specific scan tool (often a modified laptop PC) that shows more data.
What is a pending DTC?
Pending codes are caused by intermittent faults or faults that the PCM needs to see happen in two consecutive warm-up cycles to set the code. If the fault does not reappear within 40 warm-up cycles, the code will be cleared from memory.
What is load Pct%?
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.
Can a car stall if there is no DTC?
If your car’s computer hasn’t thrown any DTCs, you may want to check the following potential components or systems to find the fault. An engine can stall under different conditions, depending on the specific fault. For example, the engine may stall during acceleration, while idling, after reaching operating temperature, or stall intermittently.
What should I do if my starter motor doesn’t work?

How is DTCs used to diagnose car problems?
Since 1982, the On-Board Diagnostic (OBD) system has helped automotive technicians monitor and find problems with emission components or control systems that may have gone out of their normal operating parameters. A car’s computer uses DTCs to pinpoint a potential system’s fault.
What to do if there is no connecting wire?
Another way of identifying what the cause or the no linking could be is by testing pin to pin check with a wiring schematic while utilizing a volt meter to inspect every single wire. If you are not able to find out what the issue is, you can visit a mechanic to figure out and correct any errors.
