2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 369
The sunshade module has detected and reported via the LIN-Bus that the sunroof sunshade position select switch circuit is open or shorted to
voltage.
B369B 59
The sunshade module has detected and reported via the LIN-Bus that the sunroof sunshade position select switch has been the same active position
for 20 s after the glass has stopped moving in the requested direction due to reaching the end of the allowable motion.
Action Taken When the DTC Sets
DTC B369B is stored in the body control module (BCM) memory.
Conditions for Clearing the DTC
The BCM no longer detects a malfunction in the sunroof sunshade position select switch signal circuit.

Circuit/System Testing
Note: Because of the accessibility of the sunshade switch, perform the component testing before beginning the Circuit/System Testing.
1. Ignition OFF, disconnect the harness connector at the S90 sunroof sunshade switch.
2. Scan tool not connected, doors closed, wait 5 minutes and test for less than 10 ohm between the low reference circuit terminal 1 and ground.
瀚慖f greater than the specified value, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K62
sunroof sunshade module.
3. Ignition ON, test for 4.5-5.5 V between the reference voltage circuit terminal 4 and ground.
瀚慖f less than specified range, test the reference voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal,
replace the K62 sunroof sunshade module.
瀚慖f greater than the specified range, test the reference circuit for a short to voltage. If the circuit tests normal, replace the K62 sunroof
sunshade module.
4. If all circuits test normal, test or replace the S90 sunroof sunshade switch.
Component Testing
Static Test
1. Ignition OFF, disconnect the harness connector at the S90 sunroof sunshade switch.
2. Test for 3.6-3.7k ohm between the switch terminals 1 and 4.
瀚慖f not within the specified range, replace the S90 sunroof sunshade switch.
3. Test for 430-440 ohm between the signal terminal 1 and the low reference circuit terminal 4 while pressing the open switch.
