Honda HR-V: DTC Troubleshooting 82-13: No Signal From the Front Passenger's Weight Sensor (Front Inner Side)

Honda HR-V (2015-2021) Service Manual / Restraints / Occupant Detection System - Diagnostics / Troubleshooting / DTC Troubleshooting 82-13: No Signal From the Front Passenger's Weight Sensor (Front Inner Side)

NOTE:

  • Before doing this troubleshooting procedure, find out if the vehicle was in a collision. If so, verify that all the required components were replaced with new components of the correct part number, and that they were properly installed.
  • Before doing this troubleshooting procedure, review SRS Precautions and Procedures and General Troubleshooting Information.
  • Make sure the harness under the front passenger's seat is not pinched or interfering with other parts.

Occupant Detection System - Diagnostics

1. Problem verification:

  1. Clear the DTCs with the HDS.
  2. Turn the vehicle to the ON mode, then wait for 10 seconds.
  3. Check for DTCs with the HDS.

Occupant Detection System - Diagnostics

Is DTC 82-13 indicated?

YES

The failure is duplicated. Go to step 2.

NO

Intermittent failure, the system is OK at this time. Go to Troubleshooting Intermittent Failures. If another DTC is indicated, troubleshoot the DTC.

1. Open wire check (SWSP1 line):

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Disconnect the front passenger's weight sensor (front inner side) 3P connector (A) on the front passenger's seat wire harness.

Occupant Detection System - Diagnostics

  1. Turn the vehicle to the ON mode.
  2. Measure the voltage between test points 1 and 2.

Occupant Detection System - Diagnostics

Is there about 5 V?

YES

The SWSP1 wire is OK. Go to step 3.

NO

Open in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.

3. Shorted wire check (SWS1 line):

  1. Turn the vehicle to the OFF (LOCK) mode.
  2. Disconnect the following connector.

Front passenger's weight sensor unit connector C (6P)

  1. Measure the resistance between test points 1 and 2.

Occupant Detection System - Diagnostics

Is there an open circuit, or at least 1 MΩ?

YES

The SWS1 wire is not shorted. Go to step 4.

NO

Short to ground in the front passenger's seat wire harness; replace the front passenger's seat wire harness, then clear the DTC.

4. Shorted wire check (SWS1 line to SWS1G line):

Measure the resistance between test points 1 and 2.
