B2282

CIRCUIT DESCRIPTION
The LH Door Control Module (LDCM) has two main power feeds (high and low), and one main ground. The low power feed (battery 1) is used to provide power for the LDCM logic and internal driver operation. The high power feed (battery 2) is used to provide power for systems that draw higher amounts of current (motors, lights etc.). For most functions, the LDCM will operate properly when vehicle system voltage is between 9.0-16.0 volts. The LDCM also monitors the voltage level at battery 1 and battery 2 circuits and can determine if the voltage level received is out of range. If the voltage level is out of range in either circuit, then a malfunction is present and a DTC will set.

CONDITIONS FOR SETTING THE DTC
^ The LDCM detects battery 1 voltage range under 9.0 volts or over 16.3 volts.
^ Condition must be present for 2 seconds.

ACTION TAKEN WHEN THE DTC SETS
^ Stores a history DTC B2282 in the LDCM memory.
^ This DTC can only be set as a history code even if the malfunction is current.
^ No driver warning message will be displayed for this DTC.

CONDITIONS FOR CLEARING THE DTC
^ The LDCM detects battery 1 voltage range between 9.0-16.3 volts for longer than 2 seconds.
^ Use the IPC clearing DTCs feature
^ Use a scan tool.
