Circuit/System Testing

WARNING: This page is about a different car, the 2006 Chevrolet Monte Carlo and 2006 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition OFF, disconnect the heated seat module harness connectors C2 and C4.
  2. Test for 850-12.0K ohms of resistance between the signal circuit and the low reference circuit of the seat temperature sensor.
    • If greater than 12.0K ohms, test the signal circuit and low reference circuit for a short to voltage or an open/high resistance. If the circuits/connections test normal, replace the heated seat temperature sensor.
    • If less than 850 ohms, test the signal circuit for a short to ground. If the circuit/connections test normal, replace the heated seat temperature sensor.
  3. If all circuits/connections circuits test normal, replace the heated seat module.
