April 5, 2026: LEMON Manuals is launched! Read the announcement.

Pinpoint Test Aa: U3003:62

AA1 COMPARE THE BCM (BODY CONTROL MODULE) AND DOOR MODULE VOLTAGE PARAMETER IDENTIFICATIONS (PIDS) (MOD_SUP_V) AND (IC_VPWR)
- Ignition ON.
- Using a diagnostic scan tool, view the BCM and the DDM /PDM Parameter Identifications (PIDs).
- Using a diagnostic scan tool, view the BCM PID MOD_SUP_V.
- Using a diagnostic scan tool, view the DDM /PDM PID IC_VPWR.
Is the door module PID within 0.5 volt of the BCM PID ?
- Yes : The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.
- No : GO to AA2

AA2 CHECK THE DOOR MODULE VOLTAGE SUPPLY CIRCUIT FOR HIGH RESISTANCE

Ignition OFF.
Disconnect DDM C501A (if the DTC set in the DDM ).
Disconnect PDM C652A (if the DTC set in the PDM ).
Measure and record the battery voltage.

Measure:

CONNECTOR PIN REFERENCE

Positive Lead	Measurement/Action	Negative Lead
C501A-2		Ground

CONNECTOR PIN REFERENCE

Positive Lead	Measurement/Action	Negative Lead
C652A-2		Ground

Is the voltage reading within 0.5 volt of the recorded battery voltage?

Yes : GO to AA3
No : REPAIR the circuit.

AA3 CHECK THE DOOR MODULE GROUND CIRCUIT FOR HIGH RESISTANCE

Measure:

CONNECTOR PIN REFERENCE

Positive Lead	Measurement/Action	Negative Lead
C501A-13		Ground

CONNECTOR PIN REFERENCE

Positive Lead	Measurement/Action	Negative Lead
C652A-13		Ground

Is the resistance less than 3 ohms?

Yes : GO to AA4
No : REPAIR the circuit.

AA4 CHECK FOR CORRECT DOOR MODULE OPERATION
- Disconnect and inspect all the DDM or PDM connectors.
- Repair:
  - corrosion (install new connector or terminals - clean module pins)
  - damaged pins - install new terminals/pins
  - pushed-out pins - install new pins as necessary
- Connect the DDM or PDM 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 TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new DDM or PDM .
  REFER to: DOOR MODULE .
- 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.
