3. Test for infinite resistance between the following terminals:
* 30 and 86
* 30 and 87
* 30 and 85
* 85 and 87
瀚慖f not the specified value, replace the KR73 RUN/CRNK relay.
4. Test for less than 2 ohm between terminals 30 and 87A.
瀚慖f greater than the specified range, replace the KR73 RUN/CRNK relay.
5. Install a 3 A fused jumper wire between the relay terminal 85 and 12 V. Install a jumper wire between the relay terminal 86 and ground. Test
for less than 2 ohm between terminals 30 and 87.
瀚慖f greater than specified range, replace the KR73 RUN/CRNK relay.

DTC Descriptor
DTC B147E 02
- Battery Saver Relay Set Secondary Circuit Short to Ground
Diagnostic Fault Information
Circuit/System Description
The battery saver mode reduces the parasitic load of some modules during overseas shipment or during vehicle storage conditions. This improves
the drain time on the battery (up to 70 days without the battery going dead). When the vehicle is in transport/storage, some features may have
reduced functionality while in the battery saver mode, such as disabling the Remote Function Actuator or content theft features.
The battery saver mode incorporates a latching relay that when enabled disconnects some modules from their ignition off power or memory power
sources. For vehicles built before the mid-year 2010 model year or not flashed with 2010 model year, or newer, software, battery saver mode is
initiated by starting the vehicle and then turning the ignition key into the crank position or pushing the push button start switch (if equipped) for
greater than 15 seconds. For vehicles built after the mid-year 2010 model year or flashed with 2010 model year, or newer, software, battery saver
mode is initiated by turning on the hazard flashers, starting the vehicle, and then turning the ignition key into the crank position or pushing the push
button start switch (if equipped) for greater than 15 seconds. The mode is disengaged by repeating the previous process causing the relay to latch in
the other direction. This feature can be used as many times as necessary if the vehicle is to be stored for an extended period of time.
Conditions for Running the DTC
* The system voltage is between 9-16 V.
