VSA DTC Troubleshooting: 86-19

DTC 86-19 : F-CAN Communication With Steering Angle Sensor Malfunction

NOTE:
* Troubleshoot and repair any fuel and emissions DTCs first.
* Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information Reading and Clearing Diagnostic Trouble Codes.

1. DTC check:

DTC check
-1. Turn the ignition switch to ON (II).

-2. Clear the DTC with the HDS.

-3. Turn the ignition switch to LOCK (0), then turn it to ON (II) again.

Is DTC 86-19 indicated?
-YES- If DTC 86-19 is only indicated, go to step 2.
-YES- If DTC 86-11 is also indicated, go to DTC 86-11 VSA System.
-NO- Intermittent failure, the system is OK at this time. Refer to intermittent failures troubleshooting.

2. Open wire check (F_CAN-L, F_CAN-H lines):

Open wire check (F_CAN-L, F_CAN-H lines)
-1. Turn the ignition switch to LOCK (0).

-2. Disconnect the following connectors.





-3. Check for continuity between test points 1 and 2.














Is there continuity?
-YES- The F_CAN-L, F_CAN-H wires are OK. Go to step 3.
-NO- Repair an open in the wire between the steering angle sensor and the VSA modulator-control unit.

3. Open wire check (IG1_VSA/ABS line):

Open wire check (IG1_VSA/ABS line)
-1. Turn the ignition switch to ON (II).

-2. Measure the voltage between test points 1 and 2.









Is there battery voltage?
-YES- The IG1_VSA/ABS wire is OK. Go to step 4.
-NO- Repair an open in the wire between the No. B24 (7.5 A) fuse in the under-dash fuse/relay box and the steering angle sensor.

4. Open wire check (GND line):

Open wire check (GND line)
-1. Turn the ignition switch to LOCK (0).

-2. Reconnect the following connectors.





-3. Turn the ignition switch to ON (II).

-4. Measure the voltage between test points 1 and 2.









Is there 0.1 V or less?
-YES- The GND wire is OK. Replace the steering angle sensor Steering Angle Sensor Removal and Installation.
-NO- Repair an open in the wire between the steering angle sensor and body ground (G501).
