DESCRIPTION
If the ECU detects a trouble, it turns on the brake warning light at the same time of prohibiting ABS control.
At this time, the ECU records a DTC in memory.
Connect terminals TC and CG of the DLC3 to make the brake warning light blink and output the DTC.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 CHECK DTC
(a) Check if the ABS DTC is output (See page BC-10).
Result
2 INSPECT SKID CONTROL ECU CONNECTOR SECURELY CONNECTED
(a) Check the skid control ECU connector's connecting condition.
OK: The connector should be securely connected.
3 INSPECT BATTERY
(a) Check the battery voltage.
Standard voltage: 10 to 14 V
4 INSPECT SKID CONTROL ECU (IG1 TERMINAL VOLTAGE)
(a) Disconnect the skid control ECU connector.
(b) Turn the ignition switch to the on position.
(c) Measure the voltage according to the value(s) in the table below.
Standard voltage
5 INSPECT SKID CONTROL ECU (GND TERMINAL CONTINUITY)
(a) Disconnect the skid control ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
6 INSPECT PARKING BRAKE SWITCH
(a) Disconnect the parking brake switch connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
7 CHECK HARNESS AND CONNECTOR
(a) Disconnect the skid control ECU connector and parking brake switch.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
8 INSPECT BRAKE FLUID LEVEL WARNING SWITCH
(a) Remove the reservoir tank cap and strainer.
(b) Disconnect the brake fluid level warning switch connector.
(c) Measure the resistance according to the value(s) in the table below.
HINT: A float is placed inside the reservoir. Its position can be changed by increasing/decreasing the level of brake fluid.
Standard resistance
HINT: If there is no problem after finishing the above check, adjust the brake fluid level to the MAX level.
9 INSPECT HARNESS AND CONNECTOR (BETWEEN BRAKE FLUID LEVEL WARNING SW AND COMBINATION METER)
(a) Disconnect the combination meter connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance
10 CHECK HARNESS AND CONNECTOR (BETWEEN SKID CONTROL ECU AND COMBINATION METER ASSEMBLY)
(a) Turn the ignition switch off.
(b) Disconnect the combination meter connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance
11 INSPECT COMBINATION METER ASSEMBLY
(a) Check the combination meter assembly (See page ME- 4).
HINT: If troubleshooting has been carried out according to the PROBLEM SYMPTOMS TABLE, refer back to the table and proceed to the next step before replacing the part (See page BC-7).

Pressure Control Solenoid "B" Performance (Shift
Solenoid Valve SL2)
SYSTEM DESCRIPTION
The ECM uses signals from the vehicle speed sensor to detect the actual gear
position (1st, 2nd, 3rd, 4th
or 5th gear).
Then the ECM compares the actual gear with the shift schedule in the ECM memory
to detect mechanical
problems of the shift solenoid valves, valve b ...
Installation
1. INSTALL LOWER BALL JOINT ASSEMBLY FRONT LH
(a) Install the lower ball joint assembly front LH and
tighten the nut.
Torque: 123 N*m (1,250 kgf*cm, 91 ft.*lbf)
(b) Install a new cotter pin.
NOTICE:
If the holes for the cotter pin are not aligned,
tighten the nut further up to 60°.

Freeze frame data
1. DESCRIPTION
The ECM records vehicle and driving condition
information as freeze frame data the moment a DTC
is stored. When troubleshooting, freeze frame data
can be helpful in determining whether the vehicle
was running or stopped, whether the engine was
warmed up or not, whe ...
