(2) If the fault does not move with the CPC 2:
(a) Swap back the CPC 2 (12HL) and the CPC 1 (11HL) (Ref. AMM TASK 21-31-34-000-001) and (Ref. AMM TASK 21-31-34-400-001).
(b) Replace the VALVE-OUTFLOW (10HL), ELECTRONIC MODULE 2 (Ref. AMM TASK 21-31-51-000-002) and (Ref. AMM TASK 21-31-51-400-002).
NOTE : The electronic module 2 is connected to the electrical
____
connector 10HL-B.
(3) If the fault continues:
(a) Do a check and repair the wiring from the:
- CPC 2 controller (12HL-AA) pins 7A, 8A, 9A and 10A to the OFV controller (10HL-B) pins R, P, N and M (Ref. ASM 21-31/02).
(b) Do a check of the earthing resistance at the return ground connections (Ref. AMM 21310076000100) on:
- the CPC 2 connector 12HL-AC, pin 2 and on,
- the electronic module 2 connector 10HL-B, pin J. NOTE : The resistance value must be smaller than 20 m.ohms.
____
B. Do the test as given in the Para. 3.A.
