6.
Is the measured voltage within specifications?
YES
▶ Substitute with a known - good vehicle speed sensor and check for proper operation. If the problem is not cor-
rectd, substitute with a known - good PCM and check for proper operation. And go to "Verification of Vehicle Repair"
procedure.
NO
▶ Repair open or contact resistance in harness, and go to "Verification of Vehicle Repair" procedure.
NOTE
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized
by PCM. After testing PCM on the vehicle, use this function to reuse the PCM on the others
VERIFICATION OF VEHICLE REPAIR
EEFA2461
After a repair, it is essential to verify that the fault has been corrected.
1.
Monitor and record the Freeze Frame Data for the Diagnostic Trouble Code(DTC) which has been diagnosed.
2.
Using a Scantool, Clear the DTCs
3.
Operate the vehicle within conditions noted in the freeze frame data or enable conditions
4.
Monitor that all rediness test have been verified as " Complete "
5.
Are any DTCs present ?
YES
▶ Go to the applicable troubleshoooting procedure.
NO
▶ System is performing to specification at this time.

DTC P0504 BRAKE SWITCH "A"/"B" CORRELATION
GENERAL DESCRIPTION
EB611534
The Stop lamp switch is used to judge whether the acceleration system is abnormal or not. The stop lamp switch has a
duplex system(signals brake test or brake light) to memorize the abnormality when the signals of depressing and releasing
the brake pedal are detected simultaneously.
DTC DESCRIPTION
E8706E64
Checking output signals from both brake switch. when all of them are On or OFF simultaneously, if abnormal signal is
detected for more than 0.5 sec., an error is recognized. And if this condition lasts for certain period, PCM sets P0504.
MIL(Malfunction Indication Lamp) turns on when the malfunction lasts till cosecutive 2 driving cycle.
DTC DETECTING CONDITION
E1833C1F
