GLOW RELAY
Check continuity between glow relay terminals 3 and 5 under the fol-
lowing conditions.
Operation takes less than 1 second.
GLOW PLUG
1.
Remove glow plug connecting plate.
2.
Check glow plug resistance.
NOTE:
●
Do not bump glow plug heating element. If it is bumped,
replace glow plug with a new one.
●
If glow plug is dropped from a height of 10 cm (3.94 in) or
higher, replace with a new one.
●
If glow plug installation hole is contaminated with car-
bon, remove it with a reamer or suitable tool.
●
Hand-tighten glow plug by turning it two or three times,
then tighten using a tool to specified torque.

BRAKE SWITCH
BRAKE SWITCH
PFP:25230
Description
EBS013T6
STOP LAMP SWITCH
The stop lamp switch is installed to brake pedal bracket. The switch
senses brake pedal position and sends an ON-OFF signal to the
ECM. The ECM uses the signal to control the fuel injection control
system.
ASCD BRAKE SWITCH (MODELS WITH ASCD)
When depress on the brake pedal, ASCD brake switch is turned OFF and stop lamp switch is turned ON. ECM
detects the state of the brake pedal by this input of two kinds (ON/OFF signal)
Refer to
EC-348, "AUTOMATIC SPEED CONTROL DEVICE (ASCD)"
for the ASCD function.
CONSULT-II Reference Value in Data Monitor Mode
EBS016LE
Specification data are reference values.
ECM Terminals and Reference Value
EBS016LF
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
