2. Disconnect the negative terminal of the C1 Battery.
3. Test for less than 5 Ω between the ground circuit terminal B and ground.
⇒ If greater than the specified range, test the ground circuit for an open/high resistance.
4. Reconnect the negative terminal to the C1 Battery.
5. Ignition ON, test for greater than 11 V between the circuit terminal A and the ground circuit terminal B.
⇒ If less than the specified range, test the 12 V circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K9 Body Control Module.
6. If all circuits test normal, test or replace the A3L Sunshade - Left or A3R Sunshade - Right.
