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" .

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" .

*1: This signal is sent to the ECM through CAN communication line.
*2: ECM determines the start signal status by the signal of engine speed and battery voltage.
SYSTEM DESCRIPTION
This system improves engine operation when the air conditioner is used.
Under the following conditions, the air conditioner is turned OFF.

When the accelerator pedal is fully depressed.

When cranking the engine.

At high engine speeds.

When the engine coolant temperature becomes excessively high.

When operating power steering during low engine speed or low vehicle speed.

When engine speed is excessively low.

When refrigerant pressure is excessively low or high.
