Component part Description
TCMTCM supplies power to the starter relay and starter control relay
inside IPDM E/R when the selector lever is shifted to the P or N
position.
BCM BCM controls the starter relay inside IPDM E/R.
IPDM E/R CPU inside IPDM E/R controls the starter control relay.
Starter motorThe starter motor plunger closes and the motor is supplied with
battery power, which in turn cranks the engine, when the “S” ter-
minal is supplied with electric power.

System DescriptionINFOID:0000000003848929
The CVT senses vehicle operating conditions through various sensors. It always controls the optimum shift
position and reduces shifting and lock-up shocks.
TCM FUNCTION
The function of the TCM is to:
 Receive input signals sent from various switches and sensors.
 Determine required line pressure, shifting point, and lock-up operation.
 Send required output signals to the step motor and the respective solenoids.

P0615 START SIGNAL
DescriptionINFOID:0000000003848949
 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.

DTC CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
Immediately after performing any “DTC CONFIRMATION PROCEDURE”, always turn ignition switch OFF.
Then wait at least 10 seconds before performing the next test.
1.CHECK DTC DETECTION
With CONSULT-III
1. Turn ignition switch ON.
2. Perform “Self-Diagnostic Results” mode for “TRANSMISSION”.
Is
“P0615 STARTER RELAY/CIRC” detected?
YES >> Go to TM-42, "Diagnosis Procedure".
NO >> Check intermittent incident. Refer to GI-35, "
Intermittent Incident".
Diagnosis ProcedureINFOID:0000000003848951
1.CHECK STARTER RELAY SIGNAL
1. Turn ignition switch ON.
2. Disconnect IPDM E/R harness connector.
3. Check voltage between IPDM E/R vehicle side harness connector terminal and ground.
Is the inspection result normal?
YES >> Check starter relay and starter control relay. Refer to STR-10, "Wiring Diagram - STARTING SYS-
TEM -".
NO >> GO TO 2.
2.CHECK HARNESS BETWEEN TCM AND IPDM E/R (PART 1)
1. Turn ignition switch OFF.
2. Disconnect TCM connector.
3. Check continuity between TCM vehicle side harness connector terminal and IPDM E/R vehicle side har-
ness connector terminal.

P0615 STARTER RELAY/CIRCIf this signal is ON other than in “P” or “N” po-
sition, this is judged to be a malfunction.
(And if it is OFF in “P” or “N” position, this too
is judged to be a malfunction.) Harness or connectors
