DTC C1249/49 Open in Stop Light Switch Circuit
DESCRIPTION
This skid control ECU inputs the stop light switch signal and detects the status of brake operation.
The skid control ECU has an open detection circuit. If an open in the stop light switch input line or GND side stop light circuit is detected when the stop light switch is off, this DTC is output.

INSPECTION PROCEDURE
1 CHECK STOP LIGHT SWITCH OPERATION
(a) Check that the stop light comes on when the brake pedal is depressed, and goes off when the brake pedal is released.
OK: Stop light switch function is normal.
HINT: Check the stop light bulb as it may have burnt out.

2 INSPECT SKID CONTROL ECU (STP TERMINAL VOLTAGE)

(a) Disconnect the skid control ECU connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage

3 RECONFIRM DTC
(a) Clear the DTC (See page BC-10).
(b) Check that the same DTC is recorded (See page BC- 10).
HINT: Reinstall the sensors, connectors, etc. and restore the vehicle to its prior condition before rechecking for DTCs.
Result

REPLACE BRAKE ACTUATOR ASSEMBLY
4 INSPECT STOP LIGHT SWITCH (POWER SOURCE TERMINAL VOLTAGE)

(a) Disconnect the stop light switch connector.
(b) Measure the voltage according to the value(s) in the table below.
Standard voltage 


5 INSPECT STOP LIGHT SWITCH

(a) Measure the resistance according to the value(s) in the table below.
Standard resistance


6 CHECK HARNESS AND CONNECTOR (BETWEEN SKID CONTROL ECU AND STOP LIGHT SWITCH)

(a) Disconnect the skid control ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
