SRS DTC Troubleshooting: 46-11

DTC 46-11:

No Signal From the Right Side Impact Sensor (second)

NOTE:

Before doing this troubleshooting procedure, review SRS Precautions and Procedures and General Troubleshooting Information.
Before replacing the SRS unit, check the SRS unit software version with the HDS. If the software version is not the latest, update the SRS unit software and retest.

Is DTC 46-11 indicated?

YES	-	If DTC 46-11 is indicated alone, go to Step 4 . If DTC except 46-11 is indicated, faulty right side impact sensor (second); replace the right side impact sensor (second). ■ If DTC 44-11 and 46-11 are indicated, faulty right side impact sensor (first); replace the right side impact sensor (first). ■
NO	-	Intermittent failure, the system is OK at this time. Go to Troubleshooting Intermittent Failures. If another DTC is indicated, troubleshoot the DTC.

Are the connections OK?

YES	-	Go to Step 7 .
NO	-	Repair the poor connections and retest.

Measure the resistance between the No. 1 and No. 2 terminals of floor wire harness 2P connector. There should be an open circuit or at least 1 MΩ.

Is the resistance as specified?

YES	-	Go to Step 10 .
NO	-	Short in the floor wire harness; replace the floor wire harness.■

Measure the resistance between No. 1 terminal of floor wire harness 2P connector and body ground, and between the No. 2 terminal and body ground. There should be an open circuit or at least 1 MΩ.

Is the resistance as specified?

YES	-	Go to Step 11 .
NO	-	Short to ground in the floor wire harness; replace the floor wire harness.■

Measure the voltage between No. 1 terminal of floor wire harness 2P connector and body ground, and between the No. 2 terminal and body ground. There should be less than 1 V.

Is the voltage as specified?

YES	-	Go to Step 14 .
NO	-	Short to power in the floor wire harness; replace the floor wire harness.■

Measure the resistance between the No. 1 terminal of the floor wire harness 4P connector and the No. 2 terminal of the floor wire harness 2P connector, and between the No. 4 terminal of the floor wire harness 4P connector and the No. 1 terminal of the floor wire harness 2P connector. There should be 0−1.0 Ω.

Is the resistance as specified?

YES	-	Go to Step 16 .
NO	-	Open in the floor wire harness; replace the floor wire harness.■

Is DTC 46-11 indicated?

YES	-	Faulty SRS unit; replace the SRS unit. ■
NO	-	Faulty right side impact sensor (second); replace the right side impact sensor (second). ■
