DTC Chart.No GO to K7. - K7 CHECK BCM BAT_ST_CHRG PID
- 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 K9. No GO to K8. - K8 RELEARN BATTERY STATE OF CHARGENOTE: 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, if equipped, the DC/AC inverter.
-
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 the vehicle to sit undisturbed for at least 8 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. No GO to K9. - K9 VERIFY IN-LINE CONNECTOR
- Inspect in-line connector C1033 for secure connection.
- Disconnect: In-line connector C1033 .
- 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 CORRECT the cause as necessary. No GO to K10. - K10 CHECK FOR CORRECT BCM 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 all 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 TSBs address this concern, . CLEAR all Diagnostic Trouble Codes (DTCs) in all modules. 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.
