Inspection Procedure 3
When the ignition key is turned to "ON" (engine stopped),
the ABS warning lamp does not illuminate.
The cause may be an open circuit in the lamp power supply circuit, a blown lamp,
or an open circuit between the ABS warning lamp and the earth.
Does the ABS warning lamp illuminate when the ABS-ECU
connector B-123 is disconnected and the ignition switch is turned
to ON?
Check whether the ABS warning lamp bulb is burnt out.
Check the following connectors:
B-123, C-01, C-29 <L.H. drive vehicles>, C-128, C-210, C-213
Check the harness wire.
D Between combination meter and ABS-ECU
D Between ignition switch (IG1) and combination meter
D Between combination meter and earth
Replace the combination meter. (Refer to GROUP 54A.)
Inspection Procedure 4
Even after the engine is started, the ABS warning lamp
remains illuminated.
The cause is probably a short-circuit in the ABS warning lamp illumination circuit.
