Typical Diagnostic Reference Values
NOTE:
Footnotes are referenced throughout the Typical Diagnostic Reference Value Charts. A letter in parentheses next to a value indicates supplemental information is available.
An attempt is made to provide as much information as possible. Some vehicles may not display all input and output signals.
The Typical Diagnostic Reference Value Charts do not display fault parameter identifications (PIDs). These are PIDs which indicate a hard fault with the circuit. They display a value of FAULT or NO FAULT and are PIDs ending with the letter F.
Reference values may vary 20% depending on operating conditions, altitude, and other factors. The RPM values are axle and tire dependent.
Values are taken at an altitude of approximately 189 meters (620 ft) above sea level with the engine at normal operating temperature and accessories off.
For detailed transmission diagnostics, refer to the service information. Transmission signals may be referred to in either alpha or numeric form. For example, 1=A, 2=B, 3=C.
- Value depends on fuel tank level. Typical operating range is 15% (empty) to 85% (full).
- Value is not useful under this condition.
- Value depends on kilometers (miles) driven between completed regeneration events. For a detailed description of each displayed state, refer to Powertrain Control Software, Diesel Particulate Regeneration.
- Value depends on kilometers (miles) driven since the last regeneration event fully completed. For a detailed description of each displayed state, refer to Powertrain Control Software, Diesel Particulate Regeneration.
- Value depends on kilometers (miles) driven since the last event. For additional information, refer to Powertrain Control Software, Brake Over Accelerator.
