Technical Data and Identification
VEHICLE IDENTIFICATION LABEL
The vehicle identification plate is located on the door jamb.
Each vehicle uses a Vehicle Identification Number (VIN) that contains the model
year designation of your vehicle. The practice is in compliance with 49 CFR 565,
Code of Federal Regulations.The VIN contains 17 digits. The 10th digit is the code
for the model year of your vehicle. The example VIN below from a 1999 model
shows how this code works:
EXAMPLE VIN: 1XP 9D2X9 6 X D 345678
Model Year Serial Number
ALR TYPE PLATE
D0 00 635
The ALR type plate (load-sensing valve) is on the right-hand door pillar.
The instruction plate contains details of the axle loads and output pressures; these
correspond to the order of the axles underneath the vehicle.
So "1" is the front axle, etc.
Therefore, the data on the instruction plate relating to the driven axle is important
when checking the load-sensing valve!
