Preliminary Check
Check brake ¯uid level in reservoir
tank.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Low ¯uid level may indicate brake pad
wear or leakage from brake line.
Check brake line for leakage.

. 1: If one or more wheels spin on a rough or slippery road for 40 seconds or more, the ABS warning lamp will illuminate. This does
not indicate a malfunction. Only in the case of the short-circuit (Code Nos. 26, 22, 32 and 36), after repair the ABS warning lamp
also illuminates when the ignition switch is turned ``ON''. In this case, drive the vehicle at speeds greater than 30 km/h (19 MPH)
for approximately 1 minute as speci®ed in ``SELF-DIAGNOSIS PROCEDURE'', BR-47. Check to ensure that the ABS warning
lamp goes out while the vehicle is being driven.
. 2: The trouble code ``57'', which refers to a low power supply voltage, does not indicate that the ABS control unit is malfunctioning.
Do not replace the ABS control unit with a new one.
. 3: The trouble code ``61'' can sometimes appear when the ABS motor is not properly grounded. If it appears, be sure to check the
condition of the ABS motor ground circuit connection.

Inspection (No.2-4nozzles)
Thoroughly clean all disassembled parts with fresh kerosene or
solvent.
+If nozzle needle is damaged or fused, replace nozzle assem-
bly with a new one.
+If end of nozzle needle is seized or excessively discolored,
replace nozzle assembly.
+Check nozzle body and distance piece for proper contact. If
excessively worn or damaged, replace nozzle assembly or dis-
tance piece.
+Check distance piece and nozzle holder for proper contact. If
excessively worn or damaged, replace distance piece or nozzle
holder.
+Check nozzle spring for excessive wear or damage. If exces-
sively worn or damaged, replace it with a new spring.
Cleaning (No.2-4nozzles)
a. Do not touch the nozzle mating surface with your ®ngers.
b. To wash the nozzles, use a wooden stick and brass brush
with clean diesel fuel.
1. Remove any carbon from exterior of nozzle body (except wrap-
ping angle portion) by using Tool.
2. Clean oil sump of nozzle body using Tool.
3. Clean nozzle seat by using Tool.
This job should be performed with extra precautions, since
efficiency of nozzle depends greatly on a good nozzle seat.
