   Result

   Result	Proceed to
   Engine does not start using remote engine start function	A
   Engine does not stop using remote engine stop function	B

B → See step   12 

A: Go to next step 

1. Check if CAN communication DTCs are output. Refer to DIAGNOSIS SYSTEM [08/2015 - ] .

   HINT: 

   If any DTCs for CAN communication are output, inspect those DTCs first.

   OK

   CAN communication DTC is not output.

NG → See step   14 

OK: Go to next step 

1. Connect the Techstream to the DLC3.
2. Turn the engine switch on (IG).
3. Enter the following menus: System Select / Health Check.

   HINT: 

   If any DTCs are output, inspect those DTCs first.

   Result

   Result	Proceed to
   DTCs are not output	A
   DTCs are output	B

B → GO TO DIAGNOSTIC TROUBLE CODE CHART 

A: Go to next step 

1. Enter diagnostic mode. Refer to DIAGNOSIS SYSTEM [08/2015 - ] .
2. Check the engine stop factor.

   OK

   Hazard warning lights do not flash (No abnormal stop in the past).

NG → See step   5 

OK → See step   15 

1. Check the engine stop factor.

   Result

   Result	Proceed to
   Hazard warning lights flash 3 times (Engine speed is too high or low) [for 2GR-FE]	A
   Hazard warning lights flash 3 times (Engine speed is too high or low) [for 2AR-FE]	B
   Hazard warning lights flash 7 or 8 times (Brake pedal is pushed or vehicle speed is abnormal)	C
   Hazard warning lights flash 9 times (Immobiliser collation discrepancy)	D
   Except above (Other engine stop factor)	E

B → See step   22 

C → See step   17 

D → See step   18 

E → See step   6 

A → See step   16 

1. Confirm the engine stop factor and the vehicle condition.

   HINT: 

   • Possible other engine stop factor is listed below.
     • Hazard warning lights are flashed 1 time (engine switch on (ACC or IG))
     • Hazard warning lights are flashed 2 times (any door is unlocked)
     • Hazard warning lights are flashed 5 times (Any door or engine hood is opened)
     • Hazard warning lights are flashed 6 times (Shift lever is not in P)

   OK

   Vehicle condition differs from the engine stop factor.

NG → CORRECT VEHICLE CONDITION (OTHER ENGINE STOP FACTOR) 

OK: Go to next step 

1. Check that the fuel remaining in the tank is enough to start the engine or not.

   OK

   Engine starts with the engine switch operation.

NG → ADD FUEL 

OK: Go to next step 

1. Perform the remote engine start operation. Refer to OPERATION CHECK [08/2015 - ] .
2. Check if the engine cranks using the remote engine start function.

   Result

   Result	Proceed to
   Engine cranks	A
   Engine does not crank	B

B → See step   11 

A: Go to next step 

1. Check the wireless door lock control functions using the electrical key transmitter sub-assembly. Refer to OPERATION CHECK [08/2015 - ] .

   OK

   Wireless door lock/unlock operates normally.

NG → See step   21 

OK: Go to next step 

1. Disconnect the I13 main body ECU (multiplex network body ECU) connector.
2. Disconnect the I141 remote engine starter ECU connector.
3. Measure the resistance according to the value(s) in the below.

   Standard Resistance

   Tester Connection	Condition	Specified condition
   I13-25 (BTX) - I141-4 (BTX)	Always	Below 1 Ω
   I13-26 (BRX) - I141-3 (BRX)	Always	Below 1 Ω
   I13-25 (BTX) - Body ground	Always	10 KΩ or higher
   I13-26 (BRX) - Body ground	Always	10 KΩ or higher

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK: Go to next step 

1. Reconnect the I141 remote engine starter ECU connector.

2. Using an oscilloscope, check the waveform.
   WAVEFORM (REFERENCE)
   
   

   Item	Content
   Tester Connection	I141-3 (BRX) - Body ground
   Tool Setting	5 V/DIV., 20 ms./DIV.
   Condition	Remote engine start function is operated

   *a	Component with harness connected (Remote Engine Starter ECU)

   OK

   The remote engine starter ECU outputs a waveform within 20 seconds after the remote engine start function is activated.

NG → See step   19 

OK → See step   20 

1. Check if the engine stops when any of the following conditions is met.
   • 10 minutes elapse after the engine is started.
   • The shift lever is moved from P.
   • Any door is opened.
   • Any door is unlocked.
   • The engine hood is opened.
   • The engine switch is turned on (ACC or IG).
   • The engine speed is kept less than 200 rpm for 40 seconds.
   • The engine speed is kept more than 3000 rpm for 3 seconds.
   • Vehicle speed is input (more than 5 km/h (3 mph)).
   • Brake pedal is depressed.
   • The theft deterrent system is alarm sounding state.

   OK

   The engine stops.
