5 How to diagnose

5.1 Connections

5.1.1 Preparation

Normal testing conditions
Turn on the vehicle power supply.
Vehicle battery voltage range should be 9-14V and working voltage of CRP229 is 9-18V.
Throttle should be closed at its close position.
Ignition timing and idle speed should be within specified range; water and transmission oil temperature are within
normal working range (water temperature is 90-110 ℃ and transmission oil temperature is 50-80 ℃ ).
Select testing connectors
If CRP229 is testing vehicles equipped with universal OBD II 16 PIN diagnostic socket, please use the included
diagnostic connector. (For vehicles with non-OBD II 16 PIN diagnostic socket, a non-16 PIN connector is required.)

5.1.2 DLC Location

The DLC (Data Link Connector or Diagnostic Link Connector) is the standardized 16-cavity connector where diagnostic
code readers interface with the vehicle's on-board computer. The DLC is usually located 12 inches from the center of
the instrument panel (dash), under or around the driver's side for most vehicles. If Data Link Connector is not located
under dashboard, a label should be there telling location. For some Asian and European vehicles, the DLC is located
behind the ashtray and the ashtray must be removed to access the connector. If the DLC cannot be found, refer to the
vehicle's service manual for the location.
