Prelude L4-2056cc DOHC (1990)
^
If you can feel brake fluid coming from the return tube, one of the solenoids is leaking. Go to Solenoid Flushing.
^
It you feel no fluid coming from the return tube and the pump runs for less than 120 seconds, the cause of the Code 1 has corrected itself.
Refill the modulator reservoir to the MAX level, and return the car to the customer.
^
If you feel no fluid coming from the return tube, and if the pump runs for 120 seconds (ALB warning light comes on, LED indicates Code
1), call Engineering Tech Line with the fluid levels you recorded in step 2.
Solenoid Flushing
1.
Remove the pump relay from the under-hood relay box.
2.
Insert a spare blade terminal into each of the two rear pump relay terminal cavities in the under-hood relay box. Connect a remote starter switch to
the blade terminals. This is now the "pump relay switch."
3.
Disconnect the three modulator solenoid connectors.
4.
Connect the RED terminal from one solenoid to the battery positive (+) terminal with a remote starter switch. This is now the "solenoid switch."
Connect the BLK terminal from the same solenoid to the battery negative terminal with a jumper lead.
5.
Bleed any high pressure fluid from the maintenance bleeder with the ALB T-wrench, T/N 07HAA-SG00101.
6.
Press the pump relay switch to run the pump. After the pump has run for about five seconds, press and release the solenoid switch rapidly for 10 to
15 seconds to open and close the solenoid. Continue running the pump for about 30 seconds, then release the pump relay switch and open and
close the solenoid rapidly for another 10 to 15 seconds.
7.
Repeat steps 4-6 for the other two solenoids.
8.
Reconnect the solenoids and the pump relay.
9.
Connect the ALB Checker and turn the Mode Selector to "1." Start the engine and release the parking brake. Push the Start Test button on the
ALB Checker.
10.
While the ALB pump is running, place your finger over the top of the solenoid return tube in the modulator reservoir and check for leaks.
^
If the solenoid leakage has stopped, refill the modulator reservoir to the MAX level, and return the car to the customer.
^
If a solenoid is still leaking, call the Engineering Tech Line with the fluid levels you recorded in step 2 of the Solenoid Leak Check.
