iControl MCE Brake Voltage Not On/Off
Description:
After brake contactors are picked and controller did not receive more than 30% of the picking voltage after 1 second, this fault is generated. May be bypassed on the Diagnostics - Fault Bypass tab.
Car Reaction:
Emergency stop: Motor contactor and brake contactor immediately dropped. Fault will self clear and car will attempt to run again.
Troubleshooting:
1. Verify Brake AC input voltage at FB1 and FB2.
2. Verify FB1 and FB2 fuses are good.
3. Verify J2 connector on right side of iBox is seated properly.
4. Verify brake output voltage with multimeter on terminals B1 and B2.
5. Recalibrate brake module if applicable.
