obtained only when the yellow light is ON. Before reading the code, drive the vehicle to a level area and place
the shift lever in the PARK or NEUTRAL position. Keep the vehicle ignition ON.
Starting in 1993, all vehicles use the RABS II system. The major difference between the two systems is
the addition of keep alive memory (codes are stored, even if ignition is turned off), and a code 16 can be
set which means the system is operating properly.
TO OBTAIN THE FLASH CODE:
Locate the RABS diagnostic connector (orange/black wire) and attach a jumper wire to it and
momentarily (1 to 2 seconds) ground it to the chassis. 1.
Quickly remove the ground. When the ground is made and then removed, the RABS light will begin
to flash. 2.
The code consists of a number of short flashes and ends with a long flash. Count the short flashes and
include the following long flash in the count to obtain the code number. Example 3 short flashes and
one long flash indicated Code No. 4. The code will continue until the ignition is turned OFF. Refer to
the flashcode diagnosis charts for further instructions. 3.
