Narrative:

We were using the new ACARS automated clearance system which shows our clearance on the ACARS touch screen, along with the squawk. No call to clearance delivery is required to verify we properly received it. This is bad. Also no hard copy is generated. Also bad. The first officer was flying and had set-up the cockpit for the drake 4 departure. Our flight plan (filed clearance) was phx direct drake as filed to sfo. The ACARS screen modified this clearance by saying drake 4... As filed, but it also displays the original unmodified clearance (also bad). As the first officer had the FMC set-up for the drake 4, I thought he knew of the modification. At the 13 mi fix where we turn to 360 degree, he would not turn, even when I told him to do so. He said we were not cleared for the drake 4. I loudly and firmly commanded him to turn, and he slowly and begradingly started a very slow turn and said he didn't have a drake 4 page. And then said we were supposed to do the payso departure. I was trying very hard to contact departure but due to light aircraft frequency congestion had trouble. Finally did and they issued an immediate turn to 050 degree. Cannot explain first officer actions. Any time there is a modification to automated clearance, the modification to route should be required to be read back.

Title: TRACK DEVIATION FOR ACR ADVTECH MLG DEP PHX.

Narrative: WE WERE USING THE NEW ACARS AUTOMATED CLRNC SYS WHICH SHOWS OUR CLRNC ON THE ACARS TOUCH SCREEN, ALONG WITH THE SQUAWK. NO CALL TO CLRNC DELIVERY IS REQUIRED TO VERIFY WE PROPERLY RECEIVED IT. THIS IS BAD. ALSO NO HARD COPY IS GENERATED. ALSO BAD. THE F/O WAS FLYING AND HAD SET-UP THE COCKPIT FOR THE DRAKE 4 DEP. OUR FLT PLAN (FILED CLRNC) WAS PHX DIRECT DRAKE AS FILED TO SFO. THE ACARS SCREEN MODIFIED THIS CLRNC BY SAYING DRAKE 4... AS FILED, BUT IT ALSO DISPLAYS THE ORIGINAL UNMODIFIED CLRNC (ALSO BAD). AS THE F/O HAD THE FMC SET-UP FOR THE DRAKE 4, I THOUGHT HE KNEW OF THE MODIFICATION. AT THE 13 MI FIX WHERE WE TURN TO 360 DEG, HE WOULD NOT TURN, EVEN WHEN I TOLD HIM TO DO SO. HE SAID WE WERE NOT CLRED FOR THE DRAKE 4. I LOUDLY AND FIRMLY COMMANDED HIM TO TURN, AND HE SLOWLY AND BEGRADINGLY STARTED A VERY SLOW TURN AND SAID HE DIDN'T HAVE A DRAKE 4 PAGE. AND THEN SAID WE WERE SUPPOSED TO DO THE PAYSO DEP. I WAS TRYING VERY HARD TO CONTACT DEP BUT DUE TO LIGHT ACFT FREQ CONGESTION HAD TROUBLE. FINALLY DID AND THEY ISSUED AN IMMEDIATE TURN TO 050 DEG. CANNOT EXPLAIN F/O ACTIONS. ANY TIME THERE IS A MODIFICATION TO AUTOMATED CLRNC, THE MODIFICATION TO RTE SHOULD BE REQUIRED TO BE READ BACK.
