1)
Complete "INITIAL CONSOLE PROGRAMMING" before doing this procedure.
2)
Enter "0" in
.
3)
Enter a SPEED CAL of 300 for transmission sensors or 598 for radar sensor in
.
4)
Drive 1 mile [1 km].
CAUTION:
Do not use vehicle odometer to determine distance. Use section
lines or highway markers, or measured distance.
5)
Read DISTANCE by depressing
.
a)
DISTANCE should read a value of approximately 5280 [1000]. If it reads
between 5200-5350 [990-1010], the SPEED CAL for your vehicle is 300 or 598.
b)
If the DISTANCE display reads any other value, perform the following
calculation:
Multiply the SPEED CAL by the known distance reading, then divide the sum
by the actual value in DISTANCE display. This will give you the corrected
value to enter for SPEED CAL.
You must round off to the nearest 3 digit
whole number.
EXAMPLE:
SPEED CAL = 612 [155]
Known distance reading = 5280 [1000]
Assume the actual DISTANCE display reads 5000 [980]
ENGLISH UNITS:
METRIC UNITS:
=
612 x 5280 = 646.3
= [155] x [1000] = [158.1]
5000
[980]
6)
The corrected number to enter for SPEED CAL is 646 [158].
7)
Verify the corrected SPEED CAL number calculated above:
a)
Zero out the DISTANCE display as in Step 2.
b)
Enter the corrected SPEED CAL number as in Step 3.
c)
Repeat Steps 4 and 5a. If DISTANCE value does not read correctly repeat
Steps 5b, 6, and 7.
