Steering Angle Sensor Communication Stop Mode: Procedure

1. Disconnect the cable from the negative (-) battery terminal before measuring the resistance of the CAN main wire or CAN 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. Refer to INITIALIZATION .

NEXT: Go to next step 

1. Disconnect the C53 spiral with sensor cable sub-assembly (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
   C53-4 (CANH) - C53-3 (CANL)	Ignition switch off	54 to 69 Ω

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

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   C53-2 (ESS) - Body ground	Always	Below 1 Ω

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

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   C53-6 (BAT) - Body ground	Always	11 to 14 V
   C53-5 (IG) - Body ground	Ignition switch ON	11 to 14 V
