Circuit/System Testing
B2345 00
1. Ignition OFF, disconnect the (C1) harness connector
at the heated seat module.
2. Test for infinite resistance between the left seat
heating element supply voltage circuit terminal 3 and
ground.
➢ If less than the specified range, test the supply
voltage circuit and the heating element control
circuit for a short to ground.
3. Ignition ON, verify that a test lamp does not
illuminate between the supply voltage circuit terminal
3 and ground.
➢ If the test lamp illuminates, test the supply voltage
circuit and the heating element control circuit for a
short to voltage.
4. Test for infinite resistance between the right seat
heating element supply voltage circuit terminal 6 and
ground.
➢ If less than the specified range, test the supply
voltage circuit and the heating element control
circuit for a short to ground.
5. Ignition ON, verify that a test lamp does not
illuminate between the supply voltage circuit terminal
6 and ground.
➢ If the test lamp illuminates, test the supply voltage
circuit and the heating element control circuits for a
short to voltage.
6. If all circuits test normal, replace the heated seat
module.
B2345 13
1. Ignition OFF, disconnect the (C2, C4) harness
connector at the heated seat module.
2. Test for greater than 1.9K ohms of resistance
between the following temperature sensor signal and
low reference circuits.
– Driver seat cushion terminal 9 (C4) and terminal 6
(C2)
– Passenger seat cushion terminal 20 (C4) and
terminal 8 (C2)
➢ If less than the specified value, test for a short
between the signal and low reference circuits. If the
circuits test normal, replace the appropriate
temperature sensor.
3. If all circuits test normal, replace the heated seat
module.
B2345 42 or B2345 4B
If either DTC is set current or history, the only option is
module replacement.
