A. Do the self-test of the ECB (Ref. AMM TASK 49-00-00-710-001).
4. Fault Isolation
_______________
**ON A/C 001-003, 051-062,
A. If the test gives the maintenance message:
LOAD CTL VALVE P12:
- replace the LOAD CONTROL VALVE P12 (Ref. AMM TASK 49-51-51-000-001) and (Ref. AMM TASK 49-51-51-400-001).
(1) If the fault continues:
- disconnect connector P7 from the LOAD CONTROL VALVE P12 and check for a ground signal at pin P7/1 and P7/2. Do a repair if necessary (Ref. ASM 49-61/02).
- do a check and repair the wiring from the ECB (59KD) AB/F10, F11 to the LOAD CONTROL VALVE P12/1, 2 (Ref. ASM 49-61/02).
- do a check and repair the wiring from the ECB (59KD) AB/D7, D14 to the LOAD VALVE POSITION SWITCH P7/3, 4 (Ref. ASM 49-61/02).
(2) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and (Ref. AMM TASK 49-61-34-400-001).
R **ON A/C 063-099, 401-499,
A. If the test gives the maintenance message:
LOAD CONTROL VALVE (8050KM)
with the LRU TROUBLE SHOOT DATA menu information:
LOAD CONTROL VALVE SHOWS OPEN SWITCH FAILURE
Fault Code Number: 096
or
LOAD CONTROL VALVE SHOWS CLOSED SWITCH FAILURE
Fault Code Number: 097
or
LOAD CONTROL VALVE SHOWS NOT OPEN
Fault Code Number: 088
or
LOAD VALVE SOLENOID SHOWS CIRCUIT FAILURE
Fault Code Number: 127
- replace the LOAD CONTROL VALVE (8050KM) (Ref. AMM TASK 49-51-51-000-001) and (Ref. AMM TASK 49-51-51-400-001).
(1) If the fault continues:
- disconnect connector P7 from the LOAD CONTROL VALVE (8050KM) P12 and check for a ground signal at pin P7/1 and P7/2. Do a repair if necessary (Ref. ASM 49-61/02).
- do a check and repair the wiring from the ECB (59KD) AB/F10, F11 to the LOAD CONTROL VALVE (8050KM) P12/1, 2 (Ref. ASM 49-61/02).
- do a check and repair the wiring from the ECB (59KD) AB/D7, D14 to the LOAD VALVE POSITION SWITCH P7/3, 4 (Ref. ASM 49-61/02).
