Diagnostic Mode 01 - Obtain Data
Diagnostic Mode 01 is used to display and monitor all emissions related measured values.
Depending on scan tool and protocol used, the information displayed in diagnostic mode 01 may be referred to by different names such as Test-ID (TID), Hex-ID, Component-ID (CID), On-Board Diagnostic Monitor Identifier (OBDMID), or contain no name at all and be referenced by only a number.
Test requirement
- Coolant temperature at least 80 C.
Procedure
- Connect the scan tool.
- Start the engine and run at idle.
- Select "Diagnostic Mode 1: Obtain data.".
- From the following table, select the desired the "PID" that is to be monitored, e.g. "PID 05-Coolant temperature".
The current values of the component or system that is being monitored will be displayed on the scan tool screen.
| PID | Component or System |
|---|---|
| 04: | Calculated load value |
| 05: | Coolant temperature |
| 06: | Oxygen integrator, bank 1 |
| 07: | Oxygen adaptation value, bank 1 |
| 08: | Oxygen integrator, bank 2 |
| 09: | Oxygen adaptation value, bank 2 |
| 12: | Engine RPM |
| 13: | Vehicle speed |
| 14: | Ignition timing adjustment at 1. cyl. in direction |
| 15: | Intake air temperature (IAT) |
| 16: | Air flow quantity at Mass Air Flow (MAF) sensor |
| 17: | Throttle valve position (absolute) |
| 18: | Secondary air injection (AIR) |
| 19: | Oxygen sensor location |
| 21: | Sensor voltage Bank 1 Sensor 2 |
| 25: | Sensor voltage Bank 2 Sensor 2 |
| 28: | OBD request is designed for diagnostic of this vehicle |
| 33: | Driven distance after MIL on |
| 52: | Oxygen sensor value Bank 1 Sensor 1 |
| 56: | Oxygen sensor value Bank 2- sensor 1 |
- Switch the ignition off.
