6. Install a 3 A fused jumper wire between the signal circuit terminal 3 and the 5 V reference circuit terminal 2. Verify the scan tool BMC
Primary Piston Position Sensor A parameter is greater than 4.5 V.
瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace
the EBCM.
7. Verify the scan tool BMC Primary Piston Position Sensor B parameter is less than 1 V.
瀚慖f greater than the specified range, test the signal circuit terminal 1 for a short to voltage. If the circuit tests normal, replace the EBCM.
8. Install a 3A fused jumper wire between the signal circuit terminal 1 and the 5 V reference circuit terminal 2. Verify the scan tool BMC
Primary Piston Position Sensor B parameter is greater than 4.5 V.
瀚慖f less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace
the EBCM.
9. If all circuits test normal, replace the brake master cylinder piston position sensor.
