DESCRIPTION
When the engine is started by stop and start control, the engine stop and start ECU controls the starter assembly by activating the ST NO. 1 relay (for starter pinion operation) via voltage from terminal STA.
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):

| Blinks | DTC stored | SAE Code: P0617 |
CONFIRMATION DRIVING PATTERN
HINT:
In this case, let the vehicle idle to complete the refresh charge. The refresh charge is complete when the Data List item Status of Auxiliary Battery Charge Control changes from "Refresh Charge Mode". (Usually, idling the engine for 5 to 60 minutes with the auxiliary battery fluid temperature at 11°C (52°F) or higher, the refresh charge will be completed.)
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.
CONFIRMATION AFTER TROUBLESHOOTING
(a) Clear the DTCs.
Powertrain > Stop and Start > Clear DTCs(b) Start the engine and warm it up.
(c) Drive the vehicle at 7 km/h (4 mph) or more.
CAUTION:
When performing Confirmation Driving Pattern, obey all speed limits and traffic laws.
(d) Stop the vehicle, move the shift lever to neutral and release the clutch pedal.
(e) Keep the engine stopped by stop and start control for 1 second or more.
(f) Depress the clutch pedal and start the engine.
(g) Check that DTCs are not output.

PROCEDURE
1. | CHECK HARNESS AND CONNECTOR (ENGINE STOP AND START ECU - BBC NO. 1 FUSE AND BBC NO. 2 FUSE) |
(a) Disconnect the A66 engine stop and start ECU connector.
(b) Remove the BBC NO. 1 fuse and BBC NO. 2 fuse from the No. 1 engine room relay block.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
A66-1 (BIN2) - 2 (BBC NO. 2 fuse) | Always | Below 1 Ω |
A66-3 (BIN1) - 2 (BBC NO. 1 fuse) | Always | Below 1 Ω |
A66-1 (BIN2) - Body ground and other terminals | Always | 10 kΩ or higher |
A66-3 (BIN1) - Body ground and other terminals | Always | 10 kΩ or higher |
2 (BBC NO. 2 fuse) - Body ground and other terminals | Always | 10 kΩ or higher |
2 (BBC NO. 1 fuse) - Body ground and other terminals | Always | 10 kΩ or higher |

2. | CHECK HARNESS AND CONNECTOR (ENGINE STOP AND START ECU - ST NO. 1 RELAY) |
(a) Disconnect the H45 certification ECU (smart key ECU assembly) connector.
(b) Disconnect the A64 clutch start switch assembly connector.
(c) Disconnect the A106 ECM connector.
(d) Disconnect the A66 and A67 engine stop and start ECU connectors.
(e) Remove the ST NO. 1 relay from the No. 1 engine room relay block.
(f) Measure the resistance according to the value(s) in the table below.
