Hi:

Stll troubleshooting the SAI pump for codes P1412 and P1415...new SAI pump installed and solenoid and tested vacuum lines. still getting
the codes. The SAI pump to me is not running long enough to provide the air flow thru the valves. So, want to test it using the relay. I have
the relay off (R6). It has 4 flat blade connectors on it as shown below:

Question is, which ones do I put the jumper wire into? I believe from what I read in the RAVE on page 17-2-47:

"With a warm engine which is switched off and the SAI pump relay removed, the SAI pump can be supplied with powerby bridging terminals 87 and 30 at the relay socket.

CAUTION: Ensure that terminals 87 and 87a are not connected or bridged in any way, a short circuit will

occur."
My confusion here is the numbers on the blade connectors on the relay are: 1, 2, 3 and 5.

Any info on the CORRECT blade connector slots to use would be most appreciated.

 

I tested vacuum to the SAI solenoid when the engine is running and it is providing a good vacuum to the solenoid. The solenoid is new.
The valves are definitely opening as the exhaust gets quite a bit louder in the cabin for around 90 seconds. However, I'm only hearing
the SAI pump come on for may 5-10 seconds at first startup when temps are lower than 60 degrees.

 

I think I see what's going on here...@ atlantic british, they show the following relay for the glow plug, ABS, etc which I believe is used
for the SAI pump.


as you can see, the pins numbered 30 and 87 are refered to on the above relay. The one in my 03 disco II does not have this on the relay, so it is likely an
aftermarket one the previous owner installed.

So, given this, from the above pic, the 2 smaller flat blade connectors oriented in the same direction are the #30 and #87....correct? The other two, #85 and #86
are oriented in opposite directions.

Is my understanding correct?

 

The internet is full of answers. This is a standard pin layout for automotive fuses.

 

better to be safe than short something out. I think that this relay is on the way out as the new SAI pump is only coming on for a short few seconds. the valves stay open
for at least 90 seconds. I have good vacuum now to the SAI solenoid and since the valves are opening, the solenoid must be working correctly.
