Steering Angle Sensor Communication Stop Mode: Procedure

1. Disconnect the cable from the negative (-) battery terminal before measuring the resistance of the main wire and the branch wire.
   WARNING:

   Wait at least 90 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.

   NOTE:

   When disconnecting the cable, some systems need to be initialized after the cable is reconnected.

NEXT: Go to next step 

1. Disconnect the E11 steering angle sensor connector.

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

   Standard Resistance 

   Tester Connection	Switch Condition	Specified Condition
   E11-3 (CANH) - E11-2 (CANL)	Ignition switch off	54 to 69 Ω

NG → REPAIR OR REPLACE STEERING ANGLE SENSOR BRANCH WIRE OR CONNECTOR (CANH, CANL) 

OK: Go to next step 

1. Connect the cable to the negative (-) battery terminal.
   NOTE:

   When disconnecting the cable, some systems need to be initialized after the cable is reconnected.

2. Disconnect the E11 steering angle sensor connector.

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

   Standard Resistance 

   Tester Connection	Condition	Specified Condition
   E11-1 (ESS) - Body ground	Always	Below 1 Ω

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

   Standard Voltage 

   Tester Connection	Condition	Specified Condition
   E11-5 (BAT) - Body ground	Always	11 to 14 V
   E11-4 (IG) - Body ground	Ignition switch ON	11 to 14 V

NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

OK → See step   4
