Yaw Rate Sensor Calibration
This routine is used when a new ABS ECU or a new yaw sensor is fi tted. The yaw sensor measures a 
vehicle’s angular velocity around its vertical axis.

 Suspension ECU
Defi nition
For baseline calibration, the standard function allows changes to each corner individually, Front Left, 
Front Right, Rear Left and Rear Right.
These menu items allow calibration of the absolute value (in mm) of each height sensor.  
This is 
only required when height sensors, linkages or any parts related to the height measuring are 
replaced or reinstalled. It may also be needed after a wheel alignment. For height changes, rai-
sing or lowering the vehicle,...

Steps:
1. Preparation: go to 
http://gap-diagnostic.com/support/documents.html, download and print the  
EAS Calibration Aid and Sample EAS Calibration Calculation. Make sure the air pressure in 
each tire (or tyre...) are within specifi cation and that no heavy objects are in the vehicle.  Place 
the vehicle on a fl at, level surface in standard mode with wheels straight. While small surface 
irregularities may not reduce the accuracy of a calibration, large irregularities can make the...

5. Measure the height in millimeters of each 
corner from the bottom of the wheel arch 
to the center of the wheel. For each corner 
take note of the current height displayed 
on the cluster LCD (from outside) just be-
fore or after taking the measurement. 
Make sure the measurement of each cor-
ner is noted at the corresponding spot.

 Option 1 : Calibrating the left sensor and using the right sensor as reference.
6.  The correct calibration is achieved by adjusting only the left side of the vehicle to match the 
right. Calculate the new calibration value for the left side using the formula below. To do the 
calculation, fi ll in the table below or on the EAS Calibration Aid with the values noted for front 
corners and repeat for rear corners.

Step 7 is an example for a left side (option 1) adjustment. If a right side adjustment is  
performed, simply replace the left for right in the following text and picture.
7.  If the ‘new calibration value left’ varies less than 3mm from the old calibration value it can be 
considered good. Otherwise navigate the IIDTool to ‘Calibration-
>Adjust Front Left’ or ‘Calibra-
tion-
>Adjust Rear Left’ and use the Speed + / Menu up and Speed - / Menu down buttons to 
adjust the value to the ‘new...

6. Service/Test 
 
Defi nition
This section gives access to service routines available for a system or ECU. For example, the suspen-
sion defl ation functions are service routines. 
 
WARNING
Service Routines should only be performed by qualifi ed users 
with appropriate mechanical and electrical knowledge. Make 
sure no objects or people are near any components or systems 
related to the service routine.
Serious damage or injury can occur if the procedure is perfor-

7.  Live Values
 Defi nition
This function allows viewing the current value or state of a sensor or actuator. For a complete list of live 
values for your vehicle, please consult the functionality list on the IIDTool’s webpage.
To allow viewing of live values by the passenger, the value selected prior to driving the vehicle will 
stay displayed while the...

Viewing live values using the mobile App (from V2.0)
  Live value selection and sampling rate 
You can select up to 8 live values in the graph and 4 in the numeric display which can be viewed 
simultaneously. The sampling rate of each live value is divided by the number of live values selected. 
For example, if one live value is selected, the sampling rate will be 16 per seconds / 1 live values = 16 
samples per seconds. If 4 values are selected, 16 / 4 = 4 samples per seconds for each live...
