PINPOINT TEST A : NO POWER AT THE AC (ALTERNATING CURRENT)
POWER POINT OR THE AC (ALTERNATING CURRENT)
POWER POINT LED (LIGHT EMITTING DIODE)
INDICATOR FLASHES WITH THE KEY IN THE ON POSITION
NOTE:
The electrical device that is powered by the AC power point must not exceed 150 watts.
If the green LED is flashing, the AC power point may be overloaded, overheated or shorted. Unplug the electrical device from the AC
power point and cycle the ignition. Refer to the Owner's Literature to
determine if the electrical device is appropriate for the AC power point.
Refer to Wiring Diagrams Cell 44 for schematic and connector information.
Normal Operation and Fault Conditions
The engine must be started for the AC outlet to begin operation. No power will be provided to the AC outlet when the LED is flashing. REFER to: Direct Current/Alternating Current (DC/AC) Inverter - System Operation and Component Description (414-05 Voltage Converter/Inverter, Description and Operation).

Description |
Fault Trigger Condition |
BCM B1330:01 |
DC/AC Inverter Module: General Electrical Failure |
Sets in the BCM when the general electrical fault is detected by the direct current/alternating current (DC/AC) inverter.
|
Possible Sources
- Fuse(s)
- Direct current/alternating current (DC/AC) inverter
- AC Outlet
- Wiring, terminals or connectors
Visual Inspection and Pre-checks
- Verify the AC
outlet is not being used with the engine off for a period longer than
13 minutes without starting the engine or cycling the ignition
- Verify the cabin temperature is less than 75ºC (167ºF)
- Verify the BCM Fuse 2 (10A) is OK.
- Verify that any device being used in the AC outlet is rated at less than 150 watts
- Verify the BJB fuse 36 (40A) is OK.
- Inspect the AC outlet for damage.
|
NOTICE:
Use the correct probe adapter(s) from the Flex Probe Kit
when taking measurements. Failure to use the correct probe adapter(s)
may damage the connector.
|
A1 CHECK THE POWER OUTLET LED (LIGHT EMITTING DIODE)
STATUS |
-
Start the vehicle (Ready indicator light ON).
-
Check the LED on the AC outlet.
Did the LED illuminate?
Yes |
If the LED is on continuously,
the direct current/alternating current (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 A2
If the LED is flashing, GO to A2
|
No |
VERIFY BCM Fuse 2 (10A) and BJB fuse 36 (40A) are OK. If OK, GO to Pinpoint Test B If not OK, REFER to the Wiring Diagrams manual to identify the possible causes of the circuit short.
|
|
A2 DETERMINE IF THE DC/AC INVERTER IS OVERHEATED |
-
Determine if the direct current/alternating current (DC/AC) inverter is overheated.
Is the vehicle cabin temperature is greater than 75º
C (167º F) or has the inverter been in continuous use for a long period
of time?
Yes |
The inverter does not operate if it has overheated
or if ambient (cabin) temperatures have exceeded 75º C (166.9º F). Cycle
the ignition off and ALLOW to cool. Test the system for normal
operation.
|
|
A3 CHECK AC (ALTERNATING CURRENT)
POWER OUTLET OPERATION |
-
With the engine running, plug a device rated less than 150 watts into AC power outlet.
Is the device operating?
Yes |
If the 110V device is operating and the LED is NOT illuminated, GO to Pinpoint Test B If the device is operating and the LED is illuminated solid, the AC power outlet is operating correctly at this time.

PINPOINT TEST C : THE AC (ALTERNATING CURRENT)
POWER POINT TURNS OFF AFTER 13 MINUTES
Refer to Wiring Diagrams Cell 44 for schematic and connector information.
Normal Operation and Fault Conditions
The direct current/alternating current (DC/AC) inverter receives a signal from the BCM over the LIN whenever the engine is running.
If the direct current/alternating current (DC/AC) inverter does not
receive this message for 13 minutes, the inverter stops supplying 110
volts to the AC power outlet and the LED
indicator flashes. The system can be reset by cycling the ignition from
ON to OFF and back to ON, however the system only operates for another
13 minutes unless the signal is received from the BCM that the engine is running.
DTC Fault Trigger Conditions
DTC |
Description |
Fault Trigger Condition |
BCM B1330:08 |
DC/AC Inverter Module: Bus Signal/Message Failures |
Sets in the BCM when a general signal failure occurs on the LIN.
|
BCM B1330:02 |
DC/AC Inverter Module: General Signal Failure |
Sets in the BCM when there is a LIN communication fault from the direct current/alternating current (DC/AC) inverter.
|
Possible Sources
- Fuse(s)
- direct current/alternating current (DC/AC) inverter
-
BCM
- Wiring, terminals or connectors
Visual Inspection and Pre-checks
- Verify the concern by monitoring the AC outlet LED indicator for 13 minutes with the engine running. If the LED
indicator starts to flash after 13 minutes, continue to the pinpoint
test. If the system continues to operate normally after 13 minutes, make
sure the customer is aware of the direct current/alternating current
(DC/AC) inverter time-out function.
|
NOTICE:
Use the correct probe adapter(s) from the Flex Probe Kit
when taking measurements. Failure to use the correct probe adapter(s)
may damage the connector.
