Diagnosis Procedure
INFOID:0000000009650131
1.
CHECK STOP LAMP RELAY SIGNAL
1.
Turn ignition switch OFF.
2.
Check and adjust the installation position of stop lamp switch. Refer to
BR-7, "Inspection and Adjustment"
.
3.

DTC
Trouble diagnosis name
DTC detected condition
Possible cause
P0703
Brake Switch “B” Circuit
TCM detects malfunction in two continuous
DCs in CAN communication with BCM
• Harness or connectors
- (Stop lamp switch circuit is open or short-
ed.)
- (CAN communication line is open or
shorted.)
• Stop lamp switch
• Stop lamp relay
• BCM
When below diagnosis condition is met, if
ON/OFF of stop lamp switch signal does not
switch in two continuous DCs, the DTC is
detected at succeeding ignition switch ON
• Diagnosis Condition
- Vehicle speed is kept 30km/h (19 MPH) or
more for 10 seconds
Vehicle speed
: 30 km/h (19 MPH) or more
