I guess that means you either work or live on the wrong side of the
There is a procedure in the Jaguar Service Manual at Section 70.00.00
for performing “blink code” access on your Teves III brake system. Let
me know if you don’t have the Service Manual (everyone SHOULD get it,
together with the Parts Catalogue and Electrical Guide from JDHT for ~
$25) and I will send you the information.
Generally, there is a test connector with three sockets, next to the
ABS ECU on the right side of the boot (remove the left trim pad for
access). You want to put a jumper between (1) the socket that has the
Black wire, and (2) the socket that has the Brown/Pink wire as
(1) with the key in the off position, insert a piece of solid wire,
such as locking wire, bent in the shape of a “U”, in the Black wire
socket, and the Brown/Pink wire socket.
(2) With pen & paper in hand to record the blink codes, sit in the
driver seat and turn the key to the run position but do NOT start the
engine. Watch the Amber ABS light at the top-left of the warning
indicator row, and ~ 6 seconds after turning the key on, it should
begin to blink.
(3) Count and record the blinks.
(4) Repeat the procedure to make sure you read & recorded the codes
Each code is two-digit, such as 31 for front left sensor and 32 for
front right sensor. The “blink code” 31 would look like 3 blinks,
approximately one per second, a pause for ~ two seconds, and then one
blink. If there is a second two-digit code (and there usually is), it
will begin 6 seconds after the second digit of the first code. There
are many possible codes, the two listed above just being perhaps the
The most likely cause of the light being on is that one of your front
ABS sensor cables has failed, most likely open circuit, due to cable
shield fatigue after the outer rubber insulation has cracked.
Please let us know what you find and we can suggest some further steps.

OK, hurrying to work a few mornings ago I went over a rough RR
crossing going much faster than usual, got the ABS light just as I
hit it…it did not go out with a restart and has been on three days
