i do need a vin # ***** assist.
i need you to check if you have voltage on the red/black wire of the coolant pump when you start the car and the turn it off . the pump should run for 9 minutes after the key is turned off . you will need a volt meter to do this check please
let me know
on top of the battery fuse box check all fuses especially the 3 green fuses!!
you need to pull them and make sure that there is no black markings on the blade of the fuses then also check the 40 amp bolt in fuse make sure that is not blown. if ok then you need to make sure you have 12 volts on pin 1 and pin 3 of the 4 pin connector of the fan control module located under the drivers side frame rail under the battery.
on the connector there is #'s where the wires go in!!
ok first need to check the wiring from the pump to the 14 pin connector near the battery. reistance checkfrom pin #1 of pump to pin 13 of the 14 pin connector and pin #2 to pin 7 let me know what you have in resistance
all connectors has numbers where the terminal wire goes into the hardshell
when you do a resistance test key is always off
can you take a pic of meter and post here? i just want to make sure you are on the right setting when checking!!
that means the wire has an open then need to stretch new wire from end to end and then recheck
now to make sure did you check the male side of the 14 pin connector or the female side of the 14 pin connector?
no there is a 14 pin connector if you take the air cleaner box out in the air box area then recheck the pins stated above!!
when the air box is removed the 14 pin connector should be right there near the snorkel of the air cleaner that is still mounted .
the side where the wires going to the engine
ok here is the diagram . you need to check the v51 wires
resistance check from the fan control module pin 13 to pin 1 of the water pump and then pin 2 of the water pump to pin 7 of the 14 pin connector at the air cleaner area.
then 13 to 1 has an open that needs to be rectified first then recheck
forget 13 if 1 to 1 is good . how about 2 from pump to ground on the battery what is the resistance?
to the negative side of the battery
ok that is good!! do you have voltage at pin 4 of the fan control module (14 pin connector)
ok the next step is to unplug the radiator fan switch on the radiator drivers side and should be a triangular plug and jump 2 terminals the red wire and the red/white wire first and tell me if the fan speed is fast or slow and then jump terminals red and red/yellow and tell me the speed of the fans
ok if that is good then the fan control module's logic circuit for the pump is damaged internally and will need a new fcm.
that pump on;y runs after the car is turned off for about 10 minutes at operating temperature. if cold it may not run depends on the temp of the engine
ok let me know!!
remove the plug and run 2 wires to the pump
how about a scan test from the engine ecu
