2000 Chrysler Intrepid BaseFACTORY OEM SERVICE PROCEDURE

Sun Load Sensor Failure

WARNING: This page is about a different car, the 2002 Dodge Intrepid, 2002 Chrysler Intrepid, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: After making any repairs, perform BODY VERIFICATION TEST  under VERIFICATION TESTS.

Monitored & Set Condition

  1. When Monitored: With the ignition on.
  2. Set Condition: The BCM detects an abnormally low voltage on the sun sensor signal.

Possible Causes:

  • Sun Sensors
  • Sun Sensor Signal Circuits Short To Ground
  • Sun Sensor Signal Circuit Short To Sensor Ground
  • Body Control Module - Sun Sense Low

Testing

    NOTE: It is advisable to perform the ATC System Test before attempting to diagnose this trouble code. See ATC System Test  .
  1. Disconnect the sun sensor/VTSS LED harness connector. See Figure . With the scan tool, read the sun sensor voltage. If the voltage is .2 volt or less, go to next step. If the voltage is .2 volt or more, replace the sun sensor. See SUN SENSOR  under REMOVAL & INSTALLATION.
  2. Disconnect the BCM C1 & C2 harness connectors. See Figure and Figure . Measure the resistance between ground and the sun sensor signal circuit. If the resistance is 100 ohms or less, repair the sun sensor signal circuit for a short to ground. If the resistance is 100 ohms or more, go to next step.
  3. Measure the resistance between the sun sensor circuit and the sensor ground circuit at the sun sensor connector. If the resistance is 100 ohms or less, repair the sun sensor signal circuit for a short to the sensor ground circuit. If the resistance is 100 ohms or more replace the BCM. See BODY CONTROL MODULE  under REMOVAL & INSTALLATION.

  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
