Power latch relay parasitic draw

[89pioneer]

Hello everyone, I have 1989 jeep mj 4.0. I have been having issues with a draw on my jeep and finally did a draw test. Found my power latch relay is staying on far too long and is drawing about 1 amp at all times. What does this relay do and how do I fix this issue. THANKS!!!

When KEY OFF, after ENGINE RUNNING, power latch relay stays ON for 3-5 seconds, allowing Idle Speed Actuator (ISA) to reset for next START UP.

Any idea why it is staying on? Bad relay or??

I’m assuming when Power Latch Relay (PLR) is removed from circuit current drain goes away.

 

-Faulty PLR.
-Faulty wiring at the PLR block.
-Short to Ground between PLR_2(85) and ECU_A9.
-Faulty ECU.
