Pinpoint Test

1. Ignition OFF.
2. Start the engine.
3. Check the green LED on the AC outlet.

Is the green LED flashing? 

• Yes:
  • GO to 2  .
• No:
  • If the green LED is NOT illuminated, CHECK BJB fuse 17 (40A) and BCM fuse 32 (15A). If OK, REFER to Diagnostic Routine B: The AC Power Point LED is Never On . If not OK, identify the possible cause of the circuit short.

    Refer to the HORN_CIGAR LIGHTER - Wiring Diagrams for schematic and connector information.

  • If the green LED is illuminated continuously, the DC / AC inverter may have timed-out after 13 minutes of operation without the engine running. VERIFY correct system operation with a device rated at less than 150 watts. If there is still no power at the AC outlet, GO to 2  .

1. Ignition OFF.
2. Disconnect DC / AC Inverter C3501A.
3. Ignition ON.
4. Measure:

   DC / AC Inverter			Ground
   C3501A			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   2	CBP32 (GN/VT)		-	Ground
   4	SBB17 (RD)		-	Ground

Are the voltages greater than 10 volts? 

• Yes:
  • GO to 3  .
• No:
  • CHECK BJB fuse 17 (40A) and BCM fuse 32 (15A). If OK, REPAIR the open circuit on the affected circuit(s). If not OK, identify the possible cause of the circuit short.

    Refer to the HORN_CIGAR LIGHTER - Wiring Diagrams for schematic and connector information.

1. Ignition OFF.
2. Measure:

   DC / AC Inverter			Ground
   C3501A			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   6	GD348 (BK/YE)		-	Ground

Is the resistance less than 5 ohms? 

• Yes:
  • GO to 4  .
• No:
  • REPAIR the circuit.

1. Disconnect AC Outlet C301.
2. Disconnect DC / AC Inverter C3501B.
3. Measure:

   DC / AC Inverter			AC Outlet
   C3501B			C301
   Pin	Circuit	Measurement / Action	Pin	Circuit
   6	HYA01 (OG/GN)		3	HYA01 (OG/GN)
   3	HYA02 (OG/WH)		1	HYA02 (OG/WH)

Are the resistances less than 5 ohms? 

• Yes:
  • GO to 5  .
• No:
  • REPAIR the circuit(s).

1. Measure:

   DC / AC Inverter			DC / AC Inverter
   C3501B			C3501B
   Pin	Circuit	Measurement / Action	Pin	Circuit
   6	HYA01 (OG/GN)		3	HYA02 (OG/WH)

Is the resistance greater than 10, 000 ohms? 

• Yes:
  • GO to 6  .
• No:
  • REPAIR the circuits.

1. Measure:

   DC / AC Inverter			Ground
   C3501B			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   3	HYA02 (OG/WH)		-	Ground
   6	HYA01 (OG/GN)		-	Ground

Are the resistances greater than 10, 000 ohms? 

• Yes:
  • GO to 7  .
• No:
  • REPAIR the affected circuit(s).

1. Measure:

   AC Outlet			AC Outlet
   C301			Outlet Face
   Pin	Circuit	Measurement / Action	Pin	Circuit
   1	HYA02 (OG/WH)		1	HYA02 (OG/WH)
   3	HYA01 (OG/GN)		2	HYA01 (OG/GN)

Are the resistances less than 5 ohms? 

• Yes:
  • INSTALL a new DC / AC inverter. REFER to Direct Current-Alternating Current (DC-AC) Inverter .
• No:
  • INSTALL a new AC outlet. REFER to Alternating Current (AC) Power Point .
