-
Ignition OFF.
-
Disconnect: RETM C2949a.
-
Ignition ON.
-
Measure the voltage between the RETM C2949a-13, circuit SBP14 (BN/RD), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to P2.
No
VERIFY the Smart Junction Box (SJB) fuse 14 (10A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the Wiring Diagrams to identify the
possible causes of the circuit short. CONNECT the negative battery cable. CLEAR the DTCs. REPEAT the network test with the scan tool. See:
