DTC U1000 CAN COMMUNICATION LINEPFP:23710
DescriptionBCS001GS
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent malfunction detection ability.
Many electronic control units are equipped onto a vehicle, and each control unit shares information and links
with other control units during operation (not independent). In CAN communication, control units are con-
nected with 2 communication lines (CAN-H line, CAN-L line) allowing a high rate of information transmission
with less wiring. Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis LogicBCS001GT
Diagnostic trouble code “U1000 CAN COMM CIRCUIT” with CONSULT-II is detected when TCM cannot com-
municate to other control units.
Possible CauseBCS001GU
Harness or connectors
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureBCS001GV
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
3. Start engine and wait for at least 6 seconds.
4. If DTC is detected, go to CVT-55, "
Diagnostic Procedure" .

Diagnostic ProcedureBCS001GX
1. CHECK CAN COMMUNICATION CIRCUIT
With CONSULT-II
1. Turn ignition switch ON and start engine.
2. Select “SELF-DIAG RESULTS” mode for “TRANSMISSION”
with CONSULT-II.
Is any malfunction of the
“U1000 CAN COMM CIRCUIT” indicated?
YES >> Print out CONSULT-II screen, Go to LAN section. Refer
to LAN-49, "

DTC P0615 START SIGNAL CIRCUIT
DTC P0615 START SIGNAL CIRCUITPFP:25230
DescriptionBCS001GY
TCM controls starter relay in IPDM E/R.
TCM switches starter relay ON at “P” or “N” position and allows to crank engine.
Then it prohibits cranking other than at “P” or “N” position.
CONSULT-II Reference ValueBCS001GZ
On Board Diagnosis LogicBCS001H0
Diagnostic trouble code “P0615 STARTER RELAY/CIRC” with CONSULT-II is detected when starter relay
switched ON other than at “P” or “N” position. (Or when switched OFF at “P” or “N” position).
Possible CauseBCS001H1
Harness or connectors
(Starter relay and TCM circuit is open or shorted.)
Starter relay
DTC Confirmation ProcedureBCS001H2
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch OFF and
wait at least 10 seconds before performing the next test.
After the repair, touch “ERASE” on “SELF-DIAG RESULTS” and then perform the following procedure to con-
firm the malfunction is eliminated.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “TRANSMISSION” with
CONSULT-II.
3. Start engine.
4. Drive vehicle for at least 2 consecutive seconds.
5. If DTC is detected, go to CVT-58, "
Diagnostic Procedure" .

Diagnostic ProcedureBCS001H4
1. CHECK STARTER RELAY
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “SELECTION FROM MENU” in “DATA MONITOR” mode
for “TRANSMISSION” with CONSULT-II and check monitor
“STRTR RLY OUT”, “STRTR RLY MON”(PNP relay) ON/OFF.
Without CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Check voltage between the TCM connector terminal and
ground.
OK or NG
OK >> GO TO 3.
NG >> GO TO 2.
2. DETECT MALFUNCTIONING ITEM
Check the following:
Starter relay. Refer to PG-77, "STANDARDIZED RELAY" .
Open or short-circuit in the harness between TCM and the stater relay. Refer to CVT-57, "Wiring Diagram
— CVT — STSIG" .
Ground circuit for the starter relay. Refer to SC-15, "Wiring Diagram — START —" .
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.
3. CHECK DTC
Perform “DTC Confirmation Procedure”. Refer to CVT-56, "
DTC Confirmation Procedure" .
OK or NG
