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).

Engine Immobiliser System Malfunction
DTC B2799 Engine Immobiliser System Malfunction
DESCRIPTION
This DTC is output when the ECM detects errors in communication between the
transponder key ECU
and the ECM, or in the communication lines. This DTC is also output when an
engine start is attempted
while the ECU communication ID bet ...
Engine Coolant Temperature / Intake Air Temperature Correlation
DESCRIPTION
The ECM calculates the difference between the readings of the coolant
temperature sensor and intake air
temperature sensor. If the difference is greater than 20°C (68°F), the ECM will
judge this as a malfunction
and will set this DTC.
