Teves Anti-Lock Brakes, All Models up to year 1992

[Michael J.]

May-June 2005 Jaguar Journal reported in Jaguar Tech Corner that "Jaguar reports that the ABS pump motor relay must be replaced on all models up to 1992 if the ABS combined pressure warning switch is replaced. When this switch fails, a number of things may occur. Pump motor may run nonstop or not at all. Brake warning light or the ABS warning lights or both may come on. Fault code 61 may be present - even though braking may be normal. Part numbers are as follows: Combined pressure warning - XJS up to VIN 165791(JLM 1465) XJS from VIN 165791 (JLM 1908) Sedans JLM 1908. Relay (DAC 4506)."

I have a 90 XJS conv. that is now having this problem. In my case, the brake warning light comes on when I make a right turn and goes off after a left turn or two minutes driving straight. Now this has become a brake warning light on all the time. Braking seems normal, but I don't trust the switch won't shut off the pump.

XKs Unlimited told me that the JLM 1465 switch is no longer available. They also told me that Jaguar had a repair kit that contained both the switch and relay that is also no longer available.

Anyone know a source for the switch? The relay is still available.

It was definately the switch. I found one from a 92 XJ6 in a salvage yard.

Problem solved. If faced with a similar problem, start with the switch!

We are all going to be in trouble if a source for the switches does not become available. I wonder if Teves has a website and if the switch can be purchased through them directly?

So, my 1989 XJ6 vin SAJ should be fine?

Depends on what type of brakes your car has. If you have a Black vacuum assist with the master cylinder mounted on it, none of this applies.

If you have a seperate pump motor with an accumulator about 3" in diameter and a 1 1/2 " diameter switch with a blue connector on the pump, you have the potential to have this problem. The switch that I got in the salvage yard was from a 92 XJ6.
