B210D-BATTERY VOLTAGE LOW (RSM)

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
With the ignition on.

•

Set Condition:
Rain Sensor Module supply voltage less than 8.0 volts.

Possible Causes

VEHICLE CHARGING SYSTEM

RAIN SENSING MODULE

Diagnostic Test

CHECK FOR ACTIVE DTC: B210D-BATTERY VOLTAGE LOW

Turn the ignition on.

With the scan tool, record and erase Rain Sensor Module DTCs.

Wait 30 seconds.

With the scan tool, read Rain Sensor Module DTCs.

B2211-RAIN SENSOR MODULE INITIALIZATION PERFORMANCE

For a complete wiring diagram Refer to Section 8W.

•

When Monitored:
With the ignition on.

•

Set Condition:
This DTC is set when the internal initialization state machine is set to FAIL.

Possible Causes

WINDSHIELD

RAIN SENSOR MODULE

Diagnostic Test

CHECK FOR DELAMINATION ON THE WINDSHIELD

NOTE: If module has been reflashed or powered up while not connected to the windshield, this DTC will set.
If this is the case, reattach the RSM to the windshield and proceed.
Check the contact surface of the Rain Sensor Module to the windshield for delamination (this will resemble air bub-
bles in the contact area).

Is delamination present on the windshield?

Yes

>> Replace the windshield in accordance with the service information

TROL MODULES/FRONT CONTROL MODULE - DIAGNOSIS AND TESTING)

>> Go To 2

REPLACE THE RAIN SENSOR MODULE

With the scan tool read RSM DTCs.

Does the scan tool read: B2211-RAIN SENSOR MODULE INITIALIZATION PERFORMANCE?

Yes

>> Replace the RSM in accordance with the service information.

Perform the BODY VERIFICATION TEST — VER 1. (Refer to 8 - ELECTRICAL/ELECTRONIC CON-
TROL MODULES/FRONT CONTROL MODULE - DIAGNOSIS AND TESTING)
