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" .

DTC P0615 START SIGNAL CIRCUIT

TCM terminal data are reference values, measured between each terminal and ground.
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" .

On Board Diagnosis LogicBCS001H7
Diagnostic trouble code “P0703 BRAKE SW/CIRC” with CONSULT-II is detected when the stop lamp switch
does not switch to ON and OFF.

The stop lamp switch does not switch to ON and OFF.
Possible CauseBCS001H8

Harness or connectors
(Stop lamp switch, and unified meter and A/C amp circuit are open or shorted.)
(CAN communication line is open or shorted.)

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.

Diagnostic ProcedureBCS001HA
1. CHECK CAN COMMUNICATION LINE
Perform the self-diagnosis check. Refer to CVT-47, "
SELF-DIAGNOSTIC RESULT MODE" .
Is any malfunction of the
“U1000 CAN COMM CIRCUIT” indicated?
YES >> Check CAN communication line. Refer to CVT-53, "DTC U1000 CAN COMMUNICATION LINE" .
NO >> GO TO 2.
2. CHECK STOP LAMP SWITCH CIRCUIT
With CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “ECU INPUT SIGNALS” in “DATA MONITOR” mode for
“TRANSMISSION” with CONSULT-II.
3. Read out ON/OFF switching action of the “BRAKE SW”.
OK or NG
OK >>INSPECTION END
NG >> GO TO 3.
3. CHECK STOP LAMP SWITCH
Check continuity between stop lamp switch harness connector termi-
nals 3 and 4. Refer to CVT-160, "
Wiring Diagram — CVT — NON-
DTC" .
Check stop lamp switch after adjusting brake pedal — refer to
BR-6, "
BRAKE PEDAL" .
OK or NG
OK >> Check the following. If NG, repair or replace damaged
parts.

Harness for short or open between battery and stop lamp switch.

Harness for short or open between stop lamp switch and unified meter and A/C amp.
