- replace the SENSOR-BRK TEMP, WHEEL 1 (5GW) (Ref. AMM TASK 32-47-15-000-001) and (Ref. AMM TASK 32-47-15-400-001).
(2) If the related temperature indication does not increase on the WHEEL page:
- connect the connector of the brake temperature sensor (5GW) (Ref. AMM TASK 32-47-15-400-001)
- replace the MONITORING UNIT-BRK TEMP, L (3GW) (Ref. AMM TASK 32-47-18-000-001) and (Ref. AMM TASK 32-47-18-400-001).
(3) If the fault continues:
- do a check and repair the wiring from the BTMU (3GW) to the sensor (5GW) pins A/A, C (Ref. ASM 32-47/01).
(4) If the fault continues:
- do a check and repair the wiring from the BTMU (3GW) to the BSCU (10GG) pin A/C to pin AB/9C (Ref. ASM 32-47/01).

B. If the test gives the maintenance message BRAKE TEMP SENSOR1(5GW)/BTMU(3GW): - on the brake 1, disconnect the connector of the brake temperature
sensor 5GW (Ref. AMM TASK 32-47-15-000-001)
- on the connector of the brake temperature sensor 5GW, connect a DC Generator (0 to 50 mv) with the voltage adjusted to zero millivolt and a millivoltmeter with the polarity as follows: Terminal A: Negative. Terminal C: Positive.
- Remove the safety clip(s) and the tag(s) and close this(these) circuit breaker(s): 1GW
- on the ECAM control panel, push the WHEEL key to get the WHEEL page - on the DC generators, increase the voltage.
(1) If the related temperature indication increases on the WHEEL page
- replace the SENSOR-BRK TEMP, WHEEL 1 (5GW) (Ref. AMM TASK 32-47-15-000-001) and (Ref. AMM TASK 32-47-15-400-001).
(2) If the related temperature indication does not increase on the WHEEL page:
- connect the connector of the brake temperature sensor (5GW) (Ref. AMM TASK 32-47-15-400-001)
- replace the MONITORING UNIT-BRK TEMP, L (3GW) (Ref. AMM TASK 32-47-18-000-001) and (Ref. AMM TASK 32-47-18-400-001).
(3) If the fault continues:
- do a check and repair the wiring from the BTMU (3GW) to the sensor (5GW) pins A/A, C (Ref. ASM 32-47/01).
(4) If the fault continues:
- do a check and repair the wiring from the BTMU (3GW) to the BSCU (10GG) pin A/C to pin AB/9C (Ref. ASM 32-47/01).
**ON A/C ALL
C. Do the test given in Para. 3.A. (Ref. AMM TASK 32-46-00-740-001).
