DTC C1063 (DTC 63) – ABS Fail Safe Circuit
DESCRIPTION
The ABS control module monitors the voltage at the terminal of the solenoid circuit constantly with the ignition
switch turned ON. Also, immediately after the ignition switch is turned “ON”, perform an initial check as follows.
Switch the fail safe transistor in the order of ON → OFF → ON and check if the voltage at 6 solenoid circuit ter-
minals changes to High → Low → High. If anything faulty is found in the initial check and when the voltage at all
solenoid circuit terminals is low with the ignition switch turned ON and ABS not operated, this DTC will be set.

General Information
Statement on Cleanliness and Care
An automobile engine is a combination of many machined, honed, polished and lapped surfaces with tolerances
that are measured in the thousands of an millimeter (ten thousands of an inch).
Accordingly, when any internal engine parts are serviced, care and cleanliness are important.
Throughout this section, it should be understood that proper cleaning and protection of machined surfaces and
friction areas is part of the repair procedure. This is considered standard shop practice even if not specifically
stated.
A liberal coating of engine oil should be applied to friction areas during assembly to protect and lubricate the
surfaces on initial operation.
Whenever valve train components, pistons, piston rings, connecting rods, rod bearings, and crankshaft jour-
nal bearings are removed for service, they should be retained in order.
At the time of installation, they should be installed in the same locations and with the same mating surfaces
as when removed.
Battery cables should be disconnected before any major work is performed on the engine.
Failure to disconnect cables may result in damage to wire harness or other electrical parts.
Throughout this manual, the four cylinders of the engine are
identified by numbers; No.1 (1), No.2 (2), No.3 (3) and No.4
(4) counted from crankshaft pulley side to flywheel side.
General Information on Engine Service
THE FOLLOWING INFORMATION ON ENGINE SERVICE SHOULD BE NOTED CAREFULLY, AS IT IS
IMPORTANT IN PREVENTING DAMAGE, AND IN CONTRIBUTING TO RELIABLE ENGINE PERFORMANCE.
When raising or supporting engine for any reason, do not use a jack under oil pan. Due to small clearance
between oil pan and oil pump strainer, jacking against oil pan may cause it to be bent against strainer result-
ing in damaged oil pick-up unit.
It should be kept in mind, while working on engine, that 12-volt electrical system is capable of violent and
damaging short circuits.
When performing any work where electrical terminals can be grounded, ground cable of the battery should
be disconnected at battery.
Any time the air cleaner, throttle body or intake manifold is removed, the intake opening should be covered.
This will protect against accidental entrance of foreign material which could follow intake passage into cylin-
der and cause extensive damage when engine is started.

In the 2nd through the 4th frames, the freeze frame data of each
malfunction is stored in the order as the malfunction is detected.
These data are not updated.
Shown in the table below are examples of how freeze frame data
are stored when two or more malfunctions are detected.
Freeze Frame Data Clearance :
The freeze frame data is cleared at the same time as clearance of
diagnostic trouble code (DTC).
DATA LINK CONNECTOR (DLC)
DLC (1) is in compliance with SAEJ1962 in its installation posi-
tion, the shape of connector and pin assignment.
Serial data line (K line of ISO 9141) (3) is used for SUZUKI scan
tool or generic scan tool to communicate with ECM, TCM, Air Bag
SDM and ABS control module.
SUZUKI serial data line (6) is used for SUZUKI scan tool to com-
municate with immobilizer control module.FRAME
