H11 CHECK FOR CORRECT BCM (BODY CONTROL MODULE)
OPERATION |
-
Disconnect and inspect all the BCM connectors.
-
Repair:
-
corrosion (install new connector or terminal - clean module pins)
-
damaged or bent pins - install new terminals/pins
-
pushed-out pins - install new pins as necessary
-
Reconnect the BCM . 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 TSB . If a TSB exists for this concern,
DISCONTINUE this test and follow the TSB instructions. If no Technical
Service Bulletins (TSBs) address this concern, INSTALL a new BCM . REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Removal and Installation).
|
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.

PINPOINT TEST K: THE REAR WINDOW WIPER DOES NOT PARK AT THE CORRECT POSITION
K1 CHECK THE REAR WINDOW WIPER MOTOR VOLTAGE SUPPLY CIRCUIT FOR AN OPEN |
NOTICE:
This test uses a test lamp to simulate normal
circuit loads. Use only a Rotunda Test Lamp (SGT27000) or equivalent
250-300mA incandescent bulb test lamp. To avoid connector terminal
damage, use the Rotunda Flex Probe kit for the test lamp probe
connection to the vehicle. Do not use the test lamp probe directly on
any connector.
