DESCRIPTION
While the engine is being cranked, current flows from terminal ST2 of the ignition switch to the park/neutral position switch and also flows to terminal STA of the ECM (STA Signal).WIRING DIAGRAM
Refer to DTC P0617 (Click here).INSPECTION PROCEDURE
- NOTICE:

| 2.CHECK HARNESS AND CONNECTOR (STARTER RELAY [ST] - ECM) |
Remove the ST relay from the engine room relay block.
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
for LHD Tester Connection Condition Specified Condition ST relay terminal 2 - A38-48 (STA) Always Below 1 Ω for RHD Tester Connection Switch Condition Specified Condition ST relay terminal 2 - A52-48 (STA) Always Below 1 Ω
Reinstall the starter relay (ST).
Reconnect the ECM connector.
