DTC P0615 START SIGNAL CIRCUIT
Revision: June 20062007 Versa
DTC P0615 START SIGNAL CIRCUITPFP:25230
DescriptionUCS005YQ
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 ValueUCS005YR
On Board Diagnosis LogicUCS005YS
This is not an OBD-II self-diagnostic item.
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 CauseUCS005YT
Harness or connectors
(Starter relay and TCM circuit is open or shorted.)
Starter relay
DTC Confirmation ProcedureUCS005YU
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-74, "
Diagnostic Procedure" .

DTC P0615 START SIGNAL CIRCUIT
Revision: June 20062007 Versa
TCM terminal data are reference values, measured between each terminal and ground.
Diagnostic ProcedureUCS005YW
1. CHECK STARTER RELAY SIGNAL
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-73, "STANDARDIZED RELAY" .
Open or short-circuit in the harness between TCM and the starter relay. Refer to CVT-73, "Wiring Diagram
— CVT — STSIG" .
Ground circuit for the starter relay. Refer to SC-12, "Wiring Diagram — START —" .
OK or NG
OK >> GO TO 3.
NG >> Repair or replace damaged parts.
