The battery positive voltage (B+) is supplied to the driver door module (DDM) at the DDM connector C1 terminal 11, CKT 1540 (ORN). The DDM monitors this voltage to determine if the voltage is within a valid operating range.
The battery positive voltage (B+) exceeds 15.5 V for more than 1 second.
• | DTC B1982 is stored in the DDM memory. |
• | The DDM will not respond to any manual or memory inputs when the voltage is greater than 16 V. |
• | No driver warning message is displayed for this DTC. |
• | The DDM switch failure and position sensor failure DTCs will not set while DTC B1982 is current. |
• | The B+ voltage falls below 15 volts for approximately 1.2 seconds. |
• | The history DTC will clear after 50 ignition cycles. |
• | Use a scan tool in order to clear the history DTC. |
This DTC may set when the vehicle is placed on a battery charger set to FAST CHARGE for a long period of time.
The number(s) below refer to the step number(s) on the diagnostic table.
