Circuit/System Verification

Verify the type of vehicle and the heated seat system for which the DTC set.

If the DTC set in a hybrid vehicle without memory, refer to Circuit/System Testing below.

If the DTC set in a vehicle equipped with memory, refer to DTC B2345 (w/o HP2 with memory).

If the DTC set in a non-hybrid vehicle without memory, refer to DTC B2345 (Dealer installed).

If the DTC set in the rear heated seat module, refer to DTC B2345 (Rear seat).

Circuit/System Testing

B2345 00

1. Ignition OFF, disconnect the X1 harness connector at the HSM.

2. Test for infinite resistance between the control circuit terminal 6 and ground.

瀚慖f not the specified value, test the control circuits listed below for a short to ground:

* Driver seat cushion and seat back terminal 6

* Driver seat cushion element terminal 5

* Driver seat back element terminal 1

3. Test for infinite resistance between the control circuit terminal 3 and ground.

瀚慖f not the specified value, test the control circuits listed below for a short to ground:

* Passenger seat cushion and seat back terminal 3

* Passenger seat cushion element terminal 2

* Passenger seat back element terminal 4

4. Ignition ON, verify that a test lamp does not illuminate between the control circuit terminal 6 and ground.

瀚慖f the test lamp illuminates, test the control circuits listed below for a short to voltage:

* Driver seat cushion and seat back terminal 6

* Driver seat cushion element terminal 5

* Driver seat back element terminal 1

5. Verify that a test lamp does not illuminate between the supply voltage circuit terminal 3 and ground.
