DTC P0615:13 [ADVANCED KEYLESS ENTRY AND PUSH BUTTON START SYSTEM]

id09021c406000

ATX

DESCRIPTION
•  Open circuit in starter circuit
DETECTION CONDITION
•  Detect the mismatch voltage between starter relay and starter monitor.
―  Feedback voltage of starter relay output circuit less than 4.3 V and starter monitor input circuit higher than 4.3 V is detected under the following conditions:
•  IG1 relay output circuit is not active
•  Shift lever in P range
POSSIBLE CAUSE
•  Starter relay malfunction
•  Connector or terminal malfunction
•  Open circuit in related wiring harness
•  Keyless control module malfunction

Diagnostic Procedure

Step

Inspection

Action
1
INSPECT RELAY
•  Remove the starter relay.
•  Inspect the starter relay.
•  Is there any malfunction?
Yes
Replace the starter relay, then go to Step 4.
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 4.
No
Go to the next step.
3
INSPECT KEYLESS CONTROL MODULE
•  Reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Bring the valid key into the vehicle.
•  Measure the voltage between the following terminals and body ground with the shift lever in P range:
―  Keyless control module terminal 4B (wiring harness-side)
―  Keyless control module terminal 4AA (wiring harness-side)
•  Is the voltage more than 4 V?
Yes
Go to the next step.
No
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].)
4
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.
5
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.

DESCRIPTION
•  Open circuit in starter circuit
DETECTION CONDITION
•  Detect the mismatch voltage between starter relay and starter monitor.
―  Feedback voltage of starter relay output circuit less than 4.3 V and starter monitor input circuit higher than 4.3 V is detected under the following conditions:
•  IG1 relay output circuit is not active
•  Clutch is depressed
POSSIBLE CAUSE
•  Connector or terminal malfunction
•  Open circuit in related wiring harness
•  Keyless control module malfunction

Diagnostic Procedure

Step

Inspection

Action
1
INSPECT KEYLESS CONTROL MODULE CONNECTOR CONDITION
•  Switch the ignition to off.
•  Disconnect the negative battery cable.
•  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 4.
No
Go to the next step.
2
INSPECT STARTER RELAY CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between the following terminals:
―  Starter interlock switch terminal A (wiring harness-side) and keyless control module terminal 4AA (wiring harness-side)
―  Transaxle range switch terminal B (wiring harness-side) and keyless control module terminal 4K (wiring harness-side)
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for a possible open circuit, then go to Step 4.
3
INSPECT KEYLESS CONTROL MODULE
•  Reconnect the disconnected connectors.
•  Reconnect the negative battery cable.
•  Bring the valid key into the vehicle.
•  Measure the voltage between the following terminals and body ground with the clutch depressed:
―  Keyless control module terminal 4B (wiring harness-side)
―  Keyless control module terminal 4AA (wiring harness-side)
•  Is the voltage more than 4 V?
Yes
Go to the next step.
No
Replace the keyless control module, then go to the next step.
