DTC P0615:12 [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM]

id09021c405900

DESCRIPTION
•  Short to power supply in starter circuit
DETECTION CONDITION
•  Detect that the voltage of starter relay is higher than the specification.
―  Feedback voltage of starter relay output circuit higher than 6 V is detected under the following conditions:
•  IG1 relay output circuit is not active
•  Clutch is depressed
POSSIBLE CAUSE
•  Starter relay malfunction
•  Connector or terminal malfunction
•  Short to power supply in related wiring harness
•  Keyless control module malfunction

Diagnostic Procedure

Step

Inspection

Action
1
INSPECT RELAY
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Remove the starter relay.
•  Inspect the starter relay.
•  Is there any malfunction?
Yes
Replace the starter relay, then go to Step 5.
No
Go to the next step.
2
INSPECT KEYLESS CONTROL MODULE CONNECTOR CONDITION
•  Disconnect the keyless control module connector.
•  Inspect the connector and terminals (corrosion, damage, pin disconnection).
•  Is there any malfunction?
Yes
Repair or replace the connector or terminals, then go to Step 5.
No
Go to the next step.
3
INSPECT STARTER RELAY OUTPUT CIRCUIT FOR SHORT TO POWER SUPPLY
•  Install the starter relay.
•  Reconnect the negative battery cable.
•  Measure the voltage between the following terminals and body ground:
―  Starter relay terminal E (wiring harness-side)
―  PCM terminal 1F (wiring harness-side)
•  Is there any voltage?
Yes
Repair or replace the wiring harness for a possible short to power supply, then go to Step 5.
No
Go to the next step.
4
INSPECT KEYLESS CONTROL MODULE
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  Remove the starter relay.
•  Reconnect the keyless control module connector.
•  Reconnect the negative battery cable.
•  Measure the voltage between keyless control module terminal 4B (wiring harness-side) and body ground with the clutch depressed.
•  Is the voltage more than 6 V?
Yes
Replace the keyless control module, then go to the next step.
(See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
No
Go to the next step.
5
VERIFY TROUBLESHOOTING COMPLETED
•  Make sure to reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Clear the DTC from keyless control module memory using the M-MDS.
•  Perform the advanced keyless entry and push button start system DTC inspection using the M-MDS.
•  Is the same DTC present?
Yes
Repeat the inspection from Step 1.
If the malfunction recurs, replace the keyless control module, then go to the next step.
(See KEYLESS CONTROL MODULE REMOVAL/INSTALLATION [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
No
Go to the next step.
6
VERIFY THAT NO OTHER DTCs ARE PRESENT
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM].)
No
DTC troubleshooting completed.
