NO
If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the SBW shifter control module and the body control module. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot. If the HDS indicates NOT COMPLETED, go to step 1
- Determine possible failure area (SBW shifter control module, others)
-1. Turn the vehicle to the OFF (LOCK) mode.
-2. Disconnect the following connector.
SBW shifter control module 20P connector -3. Measure the voltage between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode SBW shifter control module 20P connector: disconnected Test point 1 SBW shifter control module 20P connector No. 7 Test point 2 Body ground Is there voltage?
YES
SBW shifter control module is OK, go to step 3.
NO
