●

This is not an OBD-II self-diagnostic item.

●

Diagnostic trouble code “P0615 STARTER RELAY/CIRC” with CONSULT-II or 14th judgement flicker
without CONSULT-II is detected when park/neutral (PNP) relay (starter relay) is switched “ON” other than
at “P” or “N” position. (Or when switched “OFF” at “P” or “N” position).

Possible Cause

ECS00EFR

●

Harness or connectors
[The park/neutral position (PNP) relay (starter relay) and TCM circuit is open or shorted.]

●

TOR

Turn ignition switch OFF.

Disconnect A/T assembly harness connector and IPDM E/R connector.

Check continuity between A/T assembly harness connector and
IPDM E/R connector.

If OK, check harness for short to ground and short to power.

Reinstall any part removed.

OK or NG

>> GO TO 3.

>> Repair open circuit or short to ground or short to power in harness or connectors.
