- replace the SENSOR, BRK TEMP, WHEEL 4 (6GW) (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 (6GW) (Ref. AMM TASK 32-47-15-400-001)
- replace the MONITORING UNIT-BRK TEMP, R (2GW) (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 (2GW) to the sensor (6GW) pins A/A, C (Ref. ASM 32-47/01).
(4) If the fault continues:
- do a check and repair the wiring from the BTMU (2GW) to the BSCU (10GG) pin A/D to pin AB/10D (Ref. ASM 32-47/01).

B. If the test gives the maintenance message BRAKE TEMP SENSOR4(6GW)/BTMU(2GW): - on the brake 4 disconnect the connector of the brake temperature sensor
6GW (Ref. AMM TASK 32-47-15-000-001)
- on the connector of the brake temperature sensor 6GW, 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 generator, increase the voltage.
(1) If the related temperature indication increases on the WHEEL page
- replace the SENSOR, BRK TEMP, WHEEL 4 (6GW) (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:

(3) If the fault continues:
- do a check and repair the wiring from the BTMU (2GW) to the sensor (6GW) pins A/A, C (Ref. ASM 32-47/01).
(4) If the fault continues:
- do a check and repair the wiring from the BTMU (2GW) to the BSCU (10GG) pin A/D to pin AB/10D (Ref. ASM 32-47/01).
