Diagnostic Steps:

1

The ABS control module is accessed via a diagnostic unit.

A. Check whether DTC is faulty

2

Inspect the battery.

A. Measure the voltage of the accumulator with the multimeter.

Standard Voltage: 11-14 V

B. Confrim whether the voltage is at a specified Value.

3

Check ABS control module harness connector

A． Inspect whether the harness connector is connected correctly.

Repair the circuit according to DTC output

Check ABS control module harness connector ( terminal voltage)

(a) Turn off the ignition switch.

B. Disconnect the harness connector of the control

module.

C. Turn on the ignition.

D. Measure the voltages between Terminals 1, 25

and 32 of the harness connector CA13 and the
body ground wire.

Standard Voltage: 11-14 V

E． Confirm if the voltage conforms to standard value.

5

Check ABS control module harness connector (grounding terminal Continuity)

A． A universal meter is used for measuring the

resistance among the terminals 13 and 38 of the
connector CA13 and the body grounding.

Standard Resistance: Less than 1 Ω

B. Confirm whether the resistance is the standard

value.
