 No Signal From the Right Side Impact Sensor (second)
NOTE:
  1. Turn the ignition switch to ON (II), then wait for 10 seconds.
Is DTC 46-11 indicated?
YES -
NO -
Intermittent failure, the system is OK at this time. Go to Troubleshooting Intermittent Failures. If another DTC is indicated, troubleshoot the DTC.
  1. Turn the ignition switch to LOCK (0).
Are the connections OK?
YES -
Go to Step 7 .
NO -
Repair the poor connections and retest.
  1. 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.■

  1. 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.■
  1. Turn the ignition switch to ON (II).

  1. 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.■
  1. Turn the ignition switch to LOCK (0).

  1. 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.■
  1. Substitute a known-good right side impact sensor (second) and recheck.
  1. Turn the ignition switch to ON (II), then wait for 10 seconds.
Is DTC 46-11 indicated?
YES -
Faulty SRS unit; replace the SRS unit.
NO -
