Communication error usually means a supply is missing.
Check yout ignition supply first then work your way around the rest.

iso 9141 that is no OBD2 DTC error that is the protocol name, (usa spec.)you scan the PCM at the 16pin DLC OBD2 port using a scan tool.
OBD2 is USA invention that other countries copied, EOBD and JOBD tool.
no country told at all. so no real easy answers ever. lacking that.
all fuses good
scan DLC port. to see DTC errors.

there are like 1000;'s of scan tools sold world wide, none told (
yes some brands of tools, yes, (I like this) Laumch(tm) example.
boots and shows he port scans. on the screen.
from old cars to new.
iso-9141 (kline)
SAE-j1850
ISO-15765 (modern cars Can_bus 2pins) 2008 and newer cars use this port. only.

Your 2014 car uses , can_Bus pins 6 and 14
if the cars DLC pin 16 has dead 12vdc on that pin (fuse is blown) commuications will fail and tool is dead

using old 1996-2007 era scan tools on this car is not going to work, .
the tool must marked, CAN_BUS READY or fails.

ENGINE STALLS. RIGHT? NOT BRAKES LOCKED UP.
STALLS AND RESTARTs EASY, CAN'T OR CRANKS SLOW?
IS BATTERY GOOD? OR JUMP CABLE STARTS WORK>
IF STARTS AGAIN IS THE GEN/BATTERY/CHARGE LAMP IN THE CLUSTER GLOWING?while still running? At idle too.
ECO IS TRICKY.
"when ECO Mode is engaged, your V8 engine has also switched to MDS Mode, which restricts the number of cylinders in use and increases fuel economy."
WHAT CAN YOU DO, DIY.
1: CHECK FUSES.
2: SCAN THE OBD2 DLC PORT FOR MDS *****. AND More

MDS+ECO can not be actually disabled.
so if fails in 6 or 8 cylinder modes, it must be repaired.
the cure (MDS) can be costly, engine valve controls
best is scan the DLC port as you drive and learn what DTC error code pop at he failure.
no better way exists. (sure scan tools that log like mine does)

What make , model an year ?

where is my DLC, ok, easy. well kinda....
weird?, no not weird, OLD,. old cars dont have OBD2, sorry.
NO COUNTRY stated, you must state that,
1993 is not a OBD2 car mostly. in any country.
that means it's OBD1 so mfg, puts the DLC where ever it wanted
and did. (huge variances)

toy was and early bird to OBD2, see? inUSA !
http://www.obdii.com/connector.html#dates

IF not OBD2
then , its FLASH codes. (easy rules)
TE1 and E1 of the Data Link Connector (DLC) 1 or 2.
now where would that be. answer

real OBD2 connector (USA cars) is just to right of steering
column,at dash edges, TOY cALLS this DLC3 (96 camry)
all scan tools with J1850 Bus work here. (older to newer)

here is a web site dedicated to DLC , musical chairs.
moves every where

1st too google hits.

The protocol is class 2 . Maybe your code reader is no good .
012 GM Class II Communications

Data Link Connector (DLC)
The data link connector (DLC) contains the following serial data links:
• Class II
• Entertainment and Comfort (E&C)
The DLC also provides a power source for the scan tool as follows:
• Unswitched voltage (B+) at DLC terminal 16 (circuit 1450)
• Ground at terminal 4 (circuit 1450) and terminal 5 (circuit 1550)

Class II Serial Data Link
The class II serial data link allows the following modules to communicate data with each other:
• Body control module (BCM)
• Electronic brake traction control module (EBTCM)
• Heater-A/C control (if equipped with RPO CJ2)
• Instrument panel cluster (IPC)
• Powertrain control module (PCM)
• Inflatable Restraint Sensing and Diagnostic Module (SDM).
The Class II serial data link allows a Scan Tool scan tool to communicate with the above modules for diagnostic and testing purposes. The Class II serial data link is located at the DLC connector terminal 2. Terminal 2 consists of the following circuits:
• Circuit 1036
• Circuit 1037
• Circuit 1128
• Circuit 1049
• Circuit 1122
• Circuit 1132
Entertainment and Comfort (E&C) Serial Data Link
The entertainment and comfort (E&C) serial data link allows a scan tool to communicate with the radio or the mobile telephone handset the remote CD player (if equipped). This communication is for diagnostic and testing purposes. The E&C serial data link is located at the DLC connector terminal 14, circuit 835.
PIN #9 goes to the air bag module .

Yes, certain 2010 Toyota Camrys were involved in both the sticking accelerator pedal and the floormat recalls.

Emergency power supply

In states where you get emission checks, it is important. If you don't have one you will also have the Check Engine light on.

Up to 99 or 2000 model maxima's arent OBD II. There is a OBD I connector located behind the fuse box cover inside the car. It is a grey connector.
