Description
Possible Cause
Action
U3002-55 Vehicle Identification
Number (VIN)
Not configured
Re-configure the relevant module as new using the
manufacturer approved diagnostic system and
re-test. If DTC remains install a new module, refer
to the new module installation note at the top of
the DTC Index
U3002-81 Vehicle Identification
Number (VIN)
Vehicle/component mis-match.
Corrupt VIN data being
transmitted, module previously
installed to other vehicle
Install original module, check for DTCs and refer to
relevant DTC Index
U3003-62 Battery voltage
Mis-match of battery voltage,
of 2 volts or lower, between
DDM/PDM and CJB
Carry out pinpoint tests associated with this DTC
using the manufacturer approved diagnostic system
General Information - Diagnostic Trouble Code (DTC) IndexDTC: Driver
Seat Module (DSM)
Description and Operation
• NOTE: If a control module or component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval program is in operation, before
the replacement of a component.
• NOTE: Generic scan tools may not read the codes listed, or may read only 5-digit codes. Match the 5 digits from the scan
tool to the first 5 digits of the 7-digit code listed to identify the fault (the last 2 digits give extra information read by the
manufacturer-approved diagnostic system).
• NOTE: When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. W hen testing resistance always take the resistance of the DMM
leads into account.
• NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
• NOTE: Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.
• NOTE: If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may
be the cause. Always check for loose connections and corroded terminals.
