Pinpoint Test R: The Accessory Protocol Interface Module (APIM) Does Not Respond To The Scan Tool
Refer to Wiring Diagram Set 14 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Module Communications Network for schematic and connector
information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Normal Operation
The Accessory Protocol Interface Module (APIM) communicates with the scan tool through the High Speed Controller Area Network (HS-CAN).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
APIM
PINPOINT TEST R: THE APIM 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.

R1 CHECK THE APIM VOLTAGE SUPPLY CIRCUIT FOR AN OPEN
-
Disconnect: APIM C3338 .
-
Ignition ON.
-
Measure the voltage between the APIM C3338-1, circuit SBP03 (BU/RD), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to R2.
No
VERIFY the Smart Junction Box (SJB) fuse 3 (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
