What is an "external slave cylinder" ?? Clutch operating cylinder maybe? Was the car functioning properly before whatever you did? If so I would inspect the work area thoroughly because something likely was unplugged.

Did you happen to short out the 12volt power system directly from the battery to ground. That error code is basically saying the ECU does not detect the CAN system which could just be a main harness isn't connected or possible a failed ECU.

Need a lot more details.

  1. Remove battery compartment plastic cover.
  2. Remove the plastic part that meets with the lower part of the windshield.
  3. take out your battery.
  4. take out the water from the battery tray.
  5. slide up the IPDM and fender fuse box, let the IPDM rest on the battery tray.
  6. unplug the drain using fingers or better.
  7. dry out as much as possible remaining droplets in the whole battery compartment with a towel.
  8. reinstall IPDM and fuse boxes on their brackets.
  9. remove IPDM and fuse boxes plastic covers.
  10. using the duster generously dry all the wires connectors at the base of the IPDM. catch the escaping water with a towel using the other hand.
  11. do the same thing in the fuse boxe.
  12. do the same thing in the wiring harness behind battery tray and coming from under it.
  13. install plastic covers on IPDM and fuses boxes.
  14. Reinstall battery.
  15. Start the car to confirm the problem went away.
  16. Stop car, reinstall the lower windshield plastic cover.
  17. Install battery compartment plastic cover.
  18. Enjoy life.

On older cars a 'gutter box' of some sort was draining the rain water coming to the bottom of the windshield and conveniently channeled it to the bottom of the car, it is called a cowl dash.on conventional design, only the wiper arms mechanism and wiper motor are installed there, end of the story. Nissan on the G35 decided they wanted to save weight and probably some money so they designed the car WITHOUT a cowl dash. Result when it rains, or you wash your beloved car, there is a waterfall running on the firewall inside the battery and Brake booster compartment. at the bottom of those boxes are holes meant to drain those boxes.

First problem: the IPDM sits low cramped in the battery compartment adjacent to the firewall, there is always a humidity risk for this device since the water flow is in it's back, common sense suggest to never place critical electrical components in the way of water ...this is only common sense though...

second problem: the battery compartment is only equipped with one drain hole at the bottom and IT COMPLETELY CLOGS WITH THE YEARS! this lead to water accumulation in the bottom of your battery compartment, with sufficient water input it can get high enough to disturb your IPDM and voila You reproduced the problem on your otherwise pristine G35! (mine was completely clogged with mud and the water level was about 1/2" high.) looking down the battery compartment does not show much, you need to bend out of the way stuff and go there with your fingers to tell.

Third problem - the plastic battery tray gets filled with water under the battery and there is no drain holes in it.
( the blame goes to the cowl dash less design ) so you carry around about a glass or two of water that splashes here and there on hard accel/braking/cornering. Removing the battery tray and drilling holes at the bottom would drain that water accumulation when it fills.


The IPDM is placed at what seems to me THE WORST PLACE EVER for a module as critical as it is.This module controls electrical power distribution across various systems and by placing it there endanger the CAN bus operation. I hope NISSAN was wise enough to improve on their electrical designs over the years...
