Starter Relay Signal Compare Failure |
DESCRIPTION
When the STA signal detected by the ECM and by the engine stop and start ECU do not match, the engine stop and start ECU stores DTC P061562 and blinks the stop and start cancel indicator.

CONFIRMATION DRIVING PATTERN
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 Techstream 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.
CONFIRMATION AFTER TROUBLESHOOTING
(a) Connect the Techstream to the DLC3.
(b) Turn the ignition switch to ON.
(c) Turn the Techstream on.
(d) Clear the DTCs.
Powertrain > Stop and Start > Clear DTCs
(e) Start the engine and warm it up.
(f) Drive the vehicle at 7 km/h (4 mph) or more.
CAUTION:
When performing Confirmation Driving Pattern, obey all speed limits and traffic laws.
(g) Depress the brake pedal and stop the vehicle.
(h) Keep the engine stopped by stop and start control. (Keep the shift lever in D.)
(i) Release the brake pedal with the shift lever in D to start the engine.
(j) Check that no DTCs are output.

HINT:
-
Using the Techstream, read the freeze frame data before troubleshooting. System condition information is recorded as freeze frame data the moment a DTC is stored. This information can be useful when troubleshooting.
