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" .
