Dtc C1063 (Dtc 63) - Abs Fail Safe Circuit - Suzuki Jimny Service Manual

DTC C1063 (DTC 63) – ABS Fail Safe Circuit
1. Ignition switch
2. ABS hydraulic unit / control module assembly
3. ABS hydraulic unit / control module connector of harness
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.
INSPECTION
Step
1 Check battery voltage. Is it about 11 V or
higher?
2 Check ABS main fuse and connection.
Is it in good condition?
3 1) Ignition switch OFF.
2) Disconnect ABS hydraulic unit / control
module connector.
3) Check proper connection to ABS hydraulic
unit / control module at terminal "A25".
4) If OK, then measure voltage between con-
nector terminal "A25" and body ground.
Is it 10 – 14 V?
3-1. Lock position
3-2. Unlock position
