Pinpoint Tests
Pinpoint Tests A: The Clock Is Inoperative
Refer to Wiring Diagram Set 44, Horn/Cigar Lighter for schematic and connector information. See: Diagrams/Electrical Diagrams/Diagrams By
Number
Normal Operation
The clock receives battery voltage from the Smart Junction Box (SJB).
This pinpoint test is intended to diagnose the following:
-
Fuse
-
Wiring, terminals or connectors
-
Clock
-
SJB
PINPOINT TEST A: THE CLOCK IS INOPERATIVE
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the
connector.
-------------------------------------------------
A1 CHECK FOR VOLTAGE TO THE CLOCK
-
Ignition OFF.
-
Disconnect: Clock C2016.
-
Measure the voltage between the clock C2016-6, circuit SBP14 (BN/RD), harness side and ground.
-
Is the voltage greater than 10 volts?
Yes
GO to A2.
No
VERIFY the SJB fuse 14 (10A) is OK. If OK, GO to A3. TEST the system for normal operation. If not OK, REFER to the Wiring Diagrams to identify
the possible causes of the circuit short. See: Diagrams/Electrical Diagrams/Diagrams By Number
-------------------------------------------------
A2 CHECK FOR VOLTAGE TO THE CLOCK USING THE CONNECTOR
-
Measure the voltage between the clock C2016-6, circuit SBP14 (BN/RD), harness side and the clock C2016-5, circuit GD150 (BK/WH), harness
side.
