GO to I6

I6 CHECK BCM (BODY CONTROL MODULE) BAT_ST_CHRG PID (PARAMETER IDENTIFICATION)
- Ignition ON.
- Using a diagnostic scan tool, view the BCM Parameter Identifications (PIDs).
- Monitor the BCM BAT_ST_CHRG PID.
Does the PID indicate 50% or more?

Yes GO to I8

No GO to I7

I7 RELEARN BATTERY STATE OF CHARGE

NOTE: The battery state of charge is too low and needs to be relearned. Refer to DESCRIPTION AND OPERATION for more information on battery state of charge.

Remove all accessories from the lighter, all power outlets and DC/AC inverter (if equipped).

NOTE: The key should not be left in the vehicle but should be left in a secure location away from the vehicle such as a lock box.

Allow vehicle to sit undisturbed for at least 6 hours.

Ignition ON.

Using a diagnostic scan tool, view the BCM Parameter Identifications (PIDs).

Monitor the BCM BAT_ST_CHRG PID.

Does the PID indicate 50% or more?

Yes	The concern may have been caused by too low of a battery state of charge. REVIEW Energy Management operation with customer and return vehicle to customer.

GO to I8

I8 VERIFY INLINE CONNECTOR
- Inspect inline connector C1045 for secure connection.
- Disconnect Inline connector C1045 .
- Inspect for:
  - corrosion (install new connector or terminals - clean module pins)
  - damaged or bent pins - install new terminals/pins
  - pushed-out pins - install new pins as necessary
Were any concerns present?

Yes REPAIR as necessary.

No GO to I9

I9 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect and inspect all BCM connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect the BCM connectors. Make sure they seat and latch correctly.

Operate the system and determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM REFER to: Body Control Module (BCM) .

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
