GENERAL DESCRIPTION

RAM is a component of BCM that consists of DDM, ADM, IPM, FAM, IMS and cluster module. Each part of
BCM is connected to one another through CAN communication line for efficient communication. Those
modules control front/rear, driver/passenger seat, cluster with electrical signal and they share information with
other modules. RAM (Rear Area Module) set up at rear-left of passenger room controls various rear lamps (tail
lamp, rear turn signal lamp, backup lamp, stop lamp, cabin lamp), window (sliding door power window, quarter
glass, rear defogger), rear wiper and oil cap door. Received multi function switch rear lamp signal from IPM
through CAN line, RAM controls Rear blower switch illumination lamp. Besides, RAM controls power sliding
door switch (RH, LH), quarter glass switch (LH/RH), rear A/C control switch.

DTC DESCRIPTION

B2598 is set when open in rear blower switch illumination circuit is detected.

DTC DETECTING CONDITION

Refer to DTC B2537.

MONITOR DTC STATUS

1. Connect scan tool to Data Link Connector (DLC).

2. Ignition "ON" & engine "OFF"

3. Select "Diagnostic Trouble Codes (DTCs)" mode and monitor "DTC Status" parameter

4. Is the DTC B2598 present?

corrosion, contamination, deterioration, or damage. Repair or replace as necessary and then go to
"VERIFICATION OF VEHICLE REPAIR" procedure.

TERMINAL AND CONNECTOR INSPECTION

Refer to DTC B2441.

POWER SUPPLY CIRCUIT INSPECTION

1. Check open in power circuit

1. Ignition "ON" & engine "OFF"

2. Measure the resistance between Rear blower switch illumination power circuit connector terminal

at RAM side (BCM-RR1-13) and Rear blower switch illumination (R42-1).

Specification: 0 ohms
