Step # 4 Motor Does Not Turn Off Within 15 Seconds Ignition "On"

STEP # 4: MOTOR DOES NOT TURN OFF WITHIN 15 SECONDS (IGNITION "ON")
A. Check fluid level per Step 1.A.
B. Install J35126 Tool per Step 2.D. and test to determine if fault is in motor and pump assembly, pressure switch, or internal booster leakage.
C. Turn ignition on. Wait 20 seconds. Monitor booster pressure on J-35126 gauge.

1. If pressure exceeds 770 psi, replace pressure switch.
2. If pressure does not reach the 540 psi - 770 psi pump shut-off range, check Port A and Port B in the booster pump reservoir (Figure 2) per Step 2.B. above. If fluid is flowing in either port, the booster is leaking internally. Repair und with Seal Repair Kit 18020067. If fluid is not flowing in either port, the motor and pump assembly is defective (unable to provide the required pressure) and should be replaced.
