P1000 code means the codes were cleared or the battery was disconnected
Powertrain Control Module (PCM) Reset
All OBDII scan tools support the powertrain control module (PCM) reset.
The PCM Reset allows the scan tool to command the PCM to clear all emission-related diagnostic information. When resetting the PCM, a DTC P1000 will be stored in the PCM until all the OBD II system monitors or components have been tested to satisfy a drive cycle, without any other faults occurring. For more information about a drive cycle, refer to Drive Cycles .
The following events occur when a PCM reset is performed:
P0411 Secondary Air Injection System Incorrect Flow Detected
- Clears the number of Diagnostic Trouble Codes (DTCs).
- Clears the DTCs.
- Clears the freeze frame data.
- Clears diagnostic monitoring test results.
- Resets status of the OBD II system monitors.
- Sets DTC P1000.
neither of these could cause a no start or no crank problem . Is the battery good an do you have good connections on the battery ? Do the headlamps show bright when on ?
