4E-30 ABS:
DTC C1063 (No. 63): ABS Fail-Safe Relay Circuit
S3RH0A4504019
Wiring Diagram
DTC Detecting Condition
ABS control module monitors the voltage at the terminal of solenoid circuit constantly with ignition switch turned ON.
Also, immediately after ignition switch is turned ON, perform initial check as follows.
Switch fail-safe relay (transistor) in the order of OFF
→
ON and check if voltage changes to Low
→
High. If anything
faulty is found in the initial check and when the voltage is low with ignition switch turned ON, this DTC will be set.

[A]: ABS hydraulic unit / control module connector E15 4. Circuit fuse box 8. ABS (10 A) fuse
1. Battery 5. Fail-safe relay (transistor) 9. ABS (60 A) fuse
2. Main fuse box 6. ABS hydraulic unit / control module assembly
3. Ignition switch 7. To solenoid valve
Step Action Yes No
1 Was “ABS Check” performed? Go to Step 2. Go to “ABS Check”.
2 Check battery voltage.
Is it about 11 V or higher?
Go to Step 3. Check charging system
referring to “Battery
Inspection in Section
1J” and “Generator Test
(Undercharged Battery
Check) in Section 1J”.
3 Check ABS (60 A) main fuse and its terminal.
Is it in good condition?
Go to Step 4. Replace fuse and check
for short circuit to
ground.
4 1) Turn ignition switch to OFF position.
2) Disconnect ABS hydraulic unit / control module
connector.
3) Check for proper connection to ABS hydraulic unit /
control module at terminal “E15-14”.
4) If OK, then measure voltage between connector terminal
“E15-14” and body ground.
Is it 10 – 14 V?
Substitute a known-
good ABS hydraulic unit
/ control module
assembly and recheck. “WHT/BLU” circuit
imperfect short to
ground.
