STOP AND START STOP AND START SYSTEM P061519 Starter Relay Circuit Current Above Threshold

DESCRIPTION

When the engine is started by stop and start control, the engine stop and start ECU controls the starter assembly by activating the STARTER relay (for starter pinion operation) via voltage from terminal STA and then, using its built-in starter delay circuit, activating the STARTER NO.2 relay (for starter motor operation) via voltage from terminal STA2.

If overcurrent is detected in the starter relay circuit, the engine stop and start ECU stores DTC P061519 and blinks the stop and start cancel indicator.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area	Warning Indicate	Memory	Note
P061519	Starter Relay Circuit Current Above Threshold	Both of the following conditions are met for 1 second (1 trip detection logic): · Ignition switch ON. · Overcurrent to STARTER relay or STARTER NO.2 relay is detected.	· Wire harness or connector · STARTER relay · STARTER NO.2 relay · Engine stop and start ECU	Blinks	DTC stored	SAE Code: P0617

CONFIRMATION DRIVING PATTERN

CONFIRMATION AFTER TROUBLESHOOTING

HINT:: ·

If the cable is disconnected from the battery terminal, stop and start control is prohibited until refresh charge is completed.

In this case, let the vehicle idle to complete the refresh charge. The refresh charge is complete when the Data List item "Status of Battery Charge Control" changes from "Refresh Charge Mode". (Usually, idling the engine for 5 to 60 minutes with the battery fluid temperature at 11°C (51°F) or higher, the refresh charge will be completed.)

·

If the GTS is not available and the Data List item "Status of Battery Charge Control" cannot be checked, charge the battery by idling the engine for approximately 5 to 60 minutes or driving the vehicle, and then drive the vehicle and check that stop and start control operates.

If the engine is started with the hood open, the system determines that a jump start has occurred. Therefore, make sure that the hood is closed before starting the engine and driving the vehicle.

·

After the refresh charge completes, turn the ignition switch off, wait for at least 30 seconds, and then start the engine again. If the vehicle enters refresh charge mode again while the engine is idling, the initial refresh charge did not properly complete, so wait for the refresh charge to complete.

·

Allow the engine to idle for 3 minutes after it is warmed up and check that the engine idle speed is within 50 rpm of the target idle speed.

Connect the GTS to the DLC3.

Turn the ignition switch to ON.

Turn the GTS on.

Clear the DTCs.

Powertrain > Stop and Start > Clear DTCs: 50002 392

Start the engine and warm it up.

Drive the vehicle at 7 km/h (4 mph) or more.

CAUTION:: When performing Confirmation Driving Pattern, obey all speed limits and traffic laws.

for Automatic Transmission:

Depress the brake pedal and stop the vehicle.

for Manual Transmission:

Stop the vehicle, move the shift lever to neutral and release the clutch pedal.

Keep the engine stopped by stop and start control for 1 second or more. (for Automatic Transmission: Keep the shift lever in D.)

for Automatic Transmission:

Release the brake pedal with the shift lever in D to start the engine.

for Manual Transmission:

Depress the clutch pedal and start the engine.

Check that DTCs are not output.

Disconnect the engine stop and start ECU connector.

Remove the BBC-1 fuse and BBC-2 fuse from the No. 1 engine room relay block and No. 1 junction block assembly.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
N31-1 (BIN2) - BBC-2 fuse terminal 2	Always	Below 1 Ω
N31-3 (BIN1) - BBC-1 fuse terminal 2	Always	Below 1 Ω
N31-1 (BIN2) or BBC-2 fuse terminal 2 - Body ground and other terminals	Always	10 kΩ or higher
N31-3 (BIN1) or BBC-1 fuse terminal 2 - Body ground and other terminals	Always	10 kΩ or higher

Result:

Proceed to
OK
NG

2.CHECK HARNESS AND CONNECTOR (ENGINE STOP AND START ECU - STARTER RELAY AND STARTER NO.2 RELAY)

REPAIR OR REPLACE HARNESS OR CONNECTOR (ENGINE STOP AND START ECU - BBC NO. 1 FUSE OR BBC NO. 2 FUSE)

2.CHECK HARNESS AND CONNECTOR (ENGINE STOP AND START ECU - STARTER RELAY AND STARTER NO.2 RELAY)

Disconnect the engine stop and start ECU connectors.

Remove the STARTER relay and STARTER NO.2 relay from the No. 1 engine room relay block and No. 1 junction block assembly.

w/ Entry and Start System:

Disconnect the certification ECU (smart key ECU assembly) connector.

for Automatic Transmission:

Disconnect the park/neutral position switch assembly connector.

for Manual Transmission:

Disconnect the clutch start switch assembly (for lower) connector.

Disconnect the ECM connector.

Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
N32-21 (STA) - 2 (STARTER relay)	Always	Below 1 Ω
N32-23 (STA2) - 2 (STARTER NO.2 relay)	Always	Below 1 Ω
N32-21 (STA) or 2 (STARTER relay) - Body ground and other terminals	Always	10 kΩ or higher
N32-23 (STA2) or 2 (STARTER NO.2 relay) - Body ground and other terminals	Always	10 kΩ or higher
N31-1 (BIN2) - N32-21 (STA)	Always	10 kΩ or higher
N31-3 (BIN1) - N32-21 (STA)	Always	10 kΩ or higher
N31-1 (BIN2) - N32-23 (STA2)	Always	10 kΩ or higher
N31-3 (BIN1) - N32-23 (STA2)	Always	10 kΩ or higher

Result:

Proceed to
OK
NG
