Do You need A Scanner to crank relearn?
These Crank Relearn Instructions may not apply to all vehicles. But they’re close to how it’s done on most cars. Connect a scanner to make sure there are no trouble codes stored in the computer’s memory.
Can a scan tool tell what the spark timing is?
Sure, what the ECM reports to the scan-tool is what timing is intended to be, so it never hurts to verify that with a timing light. Without knowing the ECM hardware and software it is impossible to tell just what is being reported to be the “spark timing”.
Why does my Nissan club have no spark?
It has no spark, the tack does not move. We changed the crank sensor, and no change. My scanner said that it should have 5 vdc on one pin of the connector and that the sensor should ohm out at 165 to 200 ohms. When I tested the plug I had 12 vdc and the sensor reads open across all the pins. Did you rebuild the motor? did it die when driving.
Can a diesel engine start with no spark?
Actually, you never ever want to use starting fluid on a diesel. Since a diesel uses a constant heating element (glow plugs or a heating grill on cummins), there is no way to control the ignition. On a gas motor, spark is variable and only one cylinder will fire at a time.
What happens when your car is not ready for an OBD test?
The status of the emission systems may also be reset by disconnecting the battery. After being reset, the emission systems on your vehicle will have a “not ready” status.
Can you erase a code with a scanner?
I’ve erased codes with a scanner before. On numerous occasions. And no, it is not the same as resetting the ECU. The deal is this: If you have a trouble code that triggers the CEL, erasing that trouble code won’t do much unless you’ve fixed what’s wrong.
Can you review all track changes at one time?
You can review and accept or reject each tracked change in sequence, accept or reject all changes at one time, delete all comments at one time, or review the items that are created by a specific reviewer.
