R B. If the test confirms the fault:
R - replace the CONTROL UNIT-CSM/G (1XE) (Ref. AMM TASK 24-24-34-000-001)
R and (Ref. AMM TASK 24-24-34-400-001).
R (1) If the fault continues:
R - replace the CSM/G (8XE) (Ref. AMM TASK 24-24-51-000-001) and (Ref.
R AMM TASK 24-24-51-400-001).
R (2) If the fault continues:
R - do a check and repair the wiring (Ref. ASM 24-24/01) between:
R . the pin 2/D of the CSM/G (8XE) and the pin A/D of the CSM/G R control unit (1XE)
R . the pin 2/E of the CSM/G (8XE) and the pin A/E of the CSM/G R control unit (1XE)
R . the pin 2/F of the CSM/G (8XE) and the pin A/G of the CSM/G R control unit (1XE)
R . the pin 2/G of the CSM/G (8XE) and the pin A/H of the CSM/G R control unit (1XE)
R . the pin 2/H of the CSM/G (8XE) and the pin A/J of the CSM/G R control unit (1XE)
R (3) If the fault continues:
R - do a check and repair the wiring (Ref. ASM 24-24/01) between:
R . the pin A/S of the CSM/G control unit (1XE) and the pin T1 of the R GLC EMER (2XE)
R . the pin A/R of the CSM/G control unit (1XE) and the pin T2 of the R GLC EMER (2XE)
R . the pin A/P of the CSM/G control unit (1XE) and the pin T3 of the R GLC EMER (2XE).
R C. If the test confirms the fault:
R - do a check of the position of the circuit breaker (27WV).
R (1) If the circuit breaker is closed:
R - do a check for 115VAC at the pin 2 of the circuit breaker (27WV).
R (a) If there is 115VAC:
R - do a check and repair the wiring between (Ref. ASM 24-35/01):
R . the pin 2 of the circuit breaker (27WV) and the first branch R point
R . the branch point and the pin AE/8B of the SDAC1 (1WV1) and R the pin AE/8B of the SDAC2 (1WV2).
