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.
