DTC (E-pretensioner)

1. Problem verification

   -1. Clear the DTCs with the HDS.

   -2. Turn the vehicle to the ON mode.

   -3. Check for DTCs with the HDS.

   DTC Description	DTC
   B2861-11 Front Passenger's E-Pretensioner Spool Sensor Signal Circuit Short to Another Signal Circuit

   Is DTC B2861-11 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Refer to intermittent failures troubleshooting.

2. E-PT MTR R GA line check 1

   -1. Check the parameter (s) below with the HDS.

   Signal	Current conditions
   	Values	Unit
   Front Passenger's Spool Sensor A Input Voltage

   When slowly pulling out the seat belt, is there battery voltage?

   YES 

   Go to step 6.

   NO 

   Go to step 3.

3. E-PT MTR R GA line check 2

   -1. Check the parameter (s) below with the HDS.

   Signal	Current conditions
   	Values	Unit
   Front Passenger's Spool Sensor A Input Voltage

   When slowly pulling out the seat belt, is there 0 V?

   YES 

   Go to step 4.

   NO 

   Go to step 5.

4. Shorted wire check (E-PT MTR R GA line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Disconnect the following connector.

   Front passenger's E-pretensioner spool sensor 3P connector

   -3. Check for continuity between test points 1 and 2 without disconnecting the E-pretensioner unit connector B (14P).

   Test condition	Vehicle OFF (LOCK) mode
   	Front passenger's E-pretensioner spool sensor 3P connector: disconnected
   Test circuit	E-PT MTR R GA
   Test point 1	E-pretensioner unit connector B (14P) No. 12 (GRY)
   Test point 2	Body ground

   Is there continuity?

   YES 

   Repair a short to ground in the wire between the E-pretensioner unit connector B (14P) of the E-pretensioner unit and the front passenger's E-pretensioner spool sensor.

   NO 

   The E-PT MTR R GA wire is OK. Faulty front passenger's E-pretensioner spool sensor; replace the front passenger's seat belt .

5. Shorted wire check (E-PT MTR R GA line to E-PT MTR R GB line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Disconnect the following connector.

   Front passenger's E-pretensioner spool sensor 3P connector

   -3. Check for continuity between test points 1 and 2 without disconnecting the E-pretensioner unit connector B (14P).

   Test condition	Vehicle OFF (LOCK) mode
   	Front passenger's E-pretensioner spool sensor 3P connector: disconnected
   Test circuit	E-PT MTR R GA, E-PT MTR R GB
   Test point 1	E-pretensioner unit connector B (14P) No. 12 (GRY)
   Test point 2	E-pretensioner unit connector B (14P) No. 6 (PUR)

   Is there continuity?

   YES 

   Repair a short in the wires between the E-pretensioner unit connector B (14P) of the E-pretensioner unit and the front passenger's E-pretensioner spool sensor.

   NO 

   The E-PT MTR R GA and E-PT MTR R GB wires are OK. Faulty front passenger's E-pretensioner spool sensor; replace the front passenger's seat belt .

6. Shorted wire check (E-PT MTR R VC line to E-PT MTR R GA line)

   -1. Turn the vehicle to the OFF (LOCK) mode.

   -2. Disconnect the following connector.

   Front passenger's E-pretensioner spool sensor 3P connector

   -3. Check for continuity between test points 1 and 2 without disconnecting the E-pretensioner unit connector B (14P).

   Test condition	Vehicle OFF (LOCK) mode
   	Front passenger's E-pretensioner spool sensor 3P connector: disconnected
   Test circuit	E-PT MTR R VC, E-PT MTR R GA
   Test point 1	E-pretensioner unit connector B (14P) No. 8 (PNK)
   Test point 2	E-pretensioner unit connector B (14P) No. 12 (GRY)
