Refer to numbered steps in figure 107.
Step 2.
Check harness connector PL1 (igure 201) at DECU, and P4 at HMA for tight connections.
Step 3.
Disconnect connectors PL1 and P4 to check pins and sockets.
Step 5.
With PL1 disconnected, check resistance of HMA (bleed valve solenoid) at harness PL1
connector sockets r and s (figure 202). Limit is 27 - 62Ω.
Step 6.
With P4 disconnected, check resistance of HMA (bleed valve solenoid) at HMA J4 connector
pins E and F. Limit is 27- 62Ω.
Step 7.
Before tightening harness connectors PL1 and P4, be sure that keyways in harness conne
c-
tors are aligned with keyways in component connectors.
