Explorer AWD V8-4.6L (2010)
Normal Operation
The Satellite Digital Audio Receiver System (SDARS) module communicates with the scan tool through the Medium Speed Controller Area Network
(MS-CAN).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
SDARS module
PINPOINT TEST K: THE SDARS MODULE DOES NOT RESPOND TO THE SCAN TOOL
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
K1 CHECK THE SDARS MODULE VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: SDARS Module C3290.
-
Ignition ON.
-
Measure the voltage between the SDARS module C3290-9, circuit SBB41 (RD), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to K2.
No
VERIFY the Battery Junction Box (BJB) fuse 41 (15A) is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the Wiring Diagrams to
identify the possible causes of the circuit short. CLEAR the DTCs. REPEAT the network test with the scan tool. See: Diagrams/Electrical
Diagrams/Diagrams By Number
-------------------------------------------------
K2 CHECK THE SDARS MODULE GROUND CIRCUIT FOR AN OPEN
-
Ignition OFF.
-
Disconnect: Negative Battery Cable.
-
Measure the resistance between the SDARS module C3290-3, circuit GD114 (BK/BU), harness side and ground.
-
Is the resistance less than 5 ohms?
Yes
