Test 17F - SUNLOAD Sensor Test
WARNING: This page is about a different car, the 1994 Eagle Vision, 1994 Dodge Intrepid, 1994 Chrysler New Yorker, 1994 Chrysler LHS, and 1994 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Perform TEST 17A before proceeding with this test.
- Connect DRB. Read ATC SUN SENSOR. If DRB displays less than SUNLOAD: 4.9 V, system is operating properly at this time. If display is not as specified, go to next step.
- Place a trouble light with a 50-watt or larger bulb on windshield, facing sunload sensor. Read ATC SUN SENSOR. If DRB displays less than SUNLOAD: 4.9 V, system is operating properly at this time. If display is not as specified, go to next step.
- Unplug sunload temperature sensor, located above center of instrument panel. Connect jumper wire between Dark Blue/Red and Gray/Tan wires at sunload sensor harness connector. Read ATC SUN SENSOR. If DRB does not display less than SUNLOAD: 0.2 V, go to next step. If DRB displays less than SUNLOAD: 0.2 V, replace sunload sensor and perform VERIFICATION TEST.
- Remove jumper wire. Connect jumper wire between Dark Blue/Red wire at sensor connector and ground. If DRB does not display less than SUNLOAD: 0.2 V, go to next step. If DRB displays below SUNLOAD: 0.2 V, repair open Gray/Tan wire between sensor connector and terminal No. 15 of Beige BCM connector, located above right kick panel.
- Remove jumper wire. Turn ignition off. Unplug BCM connectors. Using external ohmmeter, measure resistance of Dark Blue wire between sunload sensor harness connector and cavity No. 20 of Grey BCM connector. If resistance is more than 5 ohms, repair open Dark Blue wire. If resistance is less than 5 ohms, replace BCM and perform VERIFICATION TEST.
