See step  5

1. Check the hybrid control system stop factor.

   Result

   Result	Proceed to
   Hazard warning lights flash 3 times (The power source mode is not on (READY))	A
   Hazard warning lights flash 7 or 8 times (Brake pedal is depressed or vehicle speed is abnormal)	B
   Hazard warning lights flash 9 times (Immobiliser collation discrepancy)	C
   Except above (Other hybrid control system stop factor)	D

Result: 

A 

GO TO SMART KEY SYSTEM (FOR STARTING SYSTEM) 

(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2014 - 10/2015] )

Result: 

B 

GO TO ELECTRONICALLY CONTROLLED BRAKE SYSTEM 

(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2014 - 10/2015] )

Result: 

C 

GO TO IMMOBILISER SYSTEM 

(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2014 - 10/2015] )

Result: 

D 

See step  6

1. Confirm the hybrid control system stop factor and the vehicle condition.

   HINT: 

   • Possible other hybrid control system stop factors are listed below.
     • Hazard warning lights are flashed 1 time (Power switch is turned 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 hybrid control system stop factor.

Result: 

NG 

CORRECT VEHICLE CONDITION (OTHER HYBRID CONTROL SYSTEM STOP FACTOR) 

Result: 

OK 

See step  7

1. Check the wireless door lock control functions using the electrical key transmitter sub-assembly (Refer to OPERATION CHECK [10/2014 - ] ).

   OK

   Wireless door lock/unlock functions operate normally.

Result: 

NG 

GO TO WIRELESS DOOR LOCK CONTROL SYSTEM 

(Refer to HOW TO PROCEED WITH TROUBLESHOOTING [10/2014 - 10/2015] )

Result: 

OK 

See step  8

1. Disconnect the D6 main body ECU (multiplex network body ECU) connector.
2. Disconnect the D67 remote engine starter ECU connector.
3. Measure the resistance according to the value(s) in the below.

   Standard Resistance

   Tester Connection	Condition	Specified condition
   D6-25 (BTX) - D67-4 (BTX)	Always	Below 1 Ω
   D6-26 (BRX) - D67-3 (BRX)	Always	Below 1 Ω
   D6-25 (BTX) - Body ground	Always	10 kΩ or higher
   D6-26 (BRX) - Body ground	Always	10 kΩ or higher
   D67-4 (BTX) - Body ground	Always	10 kΩ or higher
   D67-3 (BRX) - Body ground	Always	10 kΩ or higher

Result: 

NG 

REPAIR OR REPLACE HARNESS OR CONNECTOR 

Result: 

OK 

See step  9

1. Reconnect the D67 remote engine starter ECU connector.
