DTC 27-11: Steering Angle Sensor Internal Circuit Malfunction

NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information (see GENERAL TROUBLESHOOTING INFORMATION ).

Turn the ignition switch to ON (II).
Clear the DTC with the HDS.
Turn the ignition switch to LOCK (0) and then back to ON (II).
Check for DTCs with the HDS.
Is DTC 27-11 indicated?

YES -Go to step 5.

NO -Intermittent failure, the system is OK at this time. Refer to INTERMITTENT FAILURES TROUBLESHOOTING
Turn the ignition switch to LOCK (0).
Disconnect the steering angle sensor 5P connector (see STEERING ANGLE SENSOR REPLACEMENT ).
Disconnect the VSA modulator-control unit 36P connector (see step 3 ).
Check for continuity between body ground and steering angle sensor 5P connector terminals No. 2, No. 3, No. 4, and No. 5 individually.

Is there continuity?

YES -Repair a short to body ground in the wire between the steering angle sensor and the VSA modulator-control unit.

NO -Go to step 9.

Check for continuity between the VSA modulator-control unit 36P connector terminal and the steering angle sensor 5P connector terminal individually (see table).

Sign	VSA Modulator-Control Unit 36P Connector Terminal	Steering Angle Sensor 5P Connector Terminal
SVCC	No. 9	No. 5
STR-A	No. 11	No. 2
STR-Z	No. 26	No. 3
STR-B	No. 27	No. 4
SGND	No. 34	No. 1

Is there continuity?

YES -Go to step 10.

NO -Repair an open in the wire between the steering angle sensor and the VSA modulator-control unit.

Substitute a known-good steering angle sensor (see STEERING ANGLE SENSOR REPLACEMENT ).
Reconnect all connectors.
Turn the ignition switch to ON (II).
Clear the DTC with the HDS.
Turn the ignition switch to LOCK (0) and then back to ON (II).
Check for DTCs with the HDS.
Is DTC 27-11 indicated?

YES -Go to step 16.

NO -Replace the original steering angle sensor (see STEERING ANGLE SENSOR REPLACEMENT ).
Update the VSA modulator-control unit if it does not have the latest software (see VSA MODULATOR-CONTROL UNIT UPDATE ).
Turn the ignition switch to LOCK (0) and then back to ON (II).
Check for DTCs with the HDS.
Is DTC 27-11 indicated?

YES -Check for loose terminals in the VSA modulator-control unit 36P connector. If the VSA modulator-control unit was updated and the symptom/indication is still present, replace the VSA modulator-control unit (see VSA MODULATOR-CONTROL UNIT REMOVAL AND INSTALLATION ).

NO -If the VSA modulator-control unit was updated, troubleshooting is complete. If any other DTCs are indicated, go to the indicated DTCS TROUBLESHOOTING .
