Del Sol L4-1.5L SOHC (1993)
Solenoids
Leak Test
NOTE: If a solenoid leaks excessively, the brake fluid level in the modulator reservoir tank will rise when operating the ABS motor. The modulator
reservoir may also overflow.
1. Connect an ohmmeter between the YEL and YEL terminals of the pressure switch connector.
2. Attach the positive (+) lead of a fully charged 12 V battery to the RED/WHT terminal of the motor connector and negative (-) lead to the GRN
terminal, and install a switch between negative lead and GRN terminal as shown.
3. Turn the switch on to allow sufficient pressure to build up within the accumulator and check for continuity. If the ohmmeter shows continuity
(pressure switch turned on), run the motor for 10 seconds more, then turn the switch off.
-
Check if the solenoid hisses or squeaks. Replace the modulator unit if the solenoid hisses or squeaks.
-
Check the pressure switch for continuity within 30 minutes. It is normal if there is continuity. If there is no continuity, a solenoid is faulty or
there is a high-pressure line leak.
Accumulator
Replacement
-
Before removing the modulator-to-accumulator high pressure line, be sure to relieve the pressure fluid from the maintenance bleeder. Refer to
Relieving Accumulator/Line Pressure above.
1. Loosen the flare nuts and remove the accumulator pipe
2. Remove the three mounting bolts and the accumulator from the modulator unit.
3. Install a new accumulator in the reverse order of removal.
