by keyboard entries rather than having to patch into a circuit.įor example, you can run radiator fan, coolant pump, fuel pump at various speeds and monitor temperatures or pressures associated with that component at the same time, such as monitoring (i) Engine Coolant Temp Sensor signal (coolant temp at top radiator), (ii) Radiator Outlet Temp Sensor signal (lower temp of coolant at bottom radiator hose) while you (iii) manually control Radiator Fan Speed, and you see all three on a screen with three bar graphs. (f) Activations (Steuern) which allow you to test operation of motors, injectors, etc. The basic diagnostic tools in INPA for E9x models:ġ) Functional Jobs: (a) see ID of ALL modules in vehicle (b) read any Fault Codes saved in ANY of those modules, all in 2 minutes from connecting to OBD II Socket.Ģ) Connect to each individual Module (DME, JBE, EKP, CAS, IHKA, etc.) to: (a) get more specific info on any fault codes saved there, (b) to see Memory History, (c) read Freeze Frame or Infospeicher Data, (d) Clear Codes, (e) “Read Status” (Status Lesen) of real-time function of components such as fuel pump, coolant pump, IHKA flap positions, Radiator Fan, switch positions, temperatures, voltages, sensor inputs to the module, etc. Anything you want to know about any senor or module you can use Inpa for. It is used for diagnostic information at the factory.

Peake has inexpensive BMW-specific tools.įor our E9X BMWs here are your options for diagnostics from cheapest to most expensive:ġ) BMW INPA or ISTA Software (Free) on a windows laptop and a $15 K+D Can cable.īMW INPA for BMW E90 full list of features/capabilities: The expensive, professional-level scanners typically provide access to most, or all, manufacturers OEM-specific information, but those scanners also typically cost $2-5K. Each manufacturers interface is different, so a scanner than can access the Ford OEM-specific information cannot, in general, access any other manufacturers OEM-specific information. The “cheap”, generic code readers CANNOT read or reset these. These devices provide NO access to the MANY other controllers in the car, like transmission, air bags, atc.Įach manufacturer also provides their own, unique OEM-specific codes, which often provide MUCH more specific faults. For many simple repairs, like a mis-fire, this is enough, for many, like turbo faults, it doesn’t even come close. This supports a wide range of generic ENGINE-ONLY codes and VERY basic functions, like clearing faults and resetting the SES light.

ALL cars since the late ’90s MUST support “Generic” access. OBD access comes in two flavors: Generic and OEM-specific. Inpa, ista, Foxwell NT520, Autel DS808 etc. Here we go for the top 4 BMW code reader for E90 models incl.
