STEP 17. Measure the voltage in the CAN_L line. Check at
intermediate connector E-122.
CAUTION
Before checking CAN bus lines and their interconnected
components, "ground" yourself, by touching a metal
object such as an unpainted pipe, this will discharge any
potentially damaging static that may have built up.
CAUTION
When measuring resistance value or voltage in CAN bus
lines, use a digital multimeter. If not using a digital multim-
eter, the equipments, which are connected through the
CAN communication lines, may be damaged.
(1) Disconnect intermediate connector E-122 and
M-ASTC-ECU connector E-121, and measure the voltage
at the female intermediate connector (control wiring
harness side).
(2) Turn the ignition switch to the "ON" position.
CAUTION
Always use the test harness when measuring the voltage
or resistance value at the female connector. If you fail to do
so, connectors may be damaged.
(3) Measure the voltage between intermediate connector
E-122 terminal 20 and body ground.
• The voltage should measure 0.5 volts or more, or 4.5
volts or less.
Q: Does the voltage measure 0.5 volts or more, or 4.5 volts
or less?
YES : Replace the M-ASTC-ECU.
NO : Go to Step 18.

STEP 18. Measure the voltage in the CAN_L line. Check at
intermediate connector E-122.
CAUTION
Before checking CAN bus lines and their interconnected
components, "ground" yourself, by touching a metal
object such as an unpainted pipe, this will discharge any
potentially damaging static that may have built up.
CAUTION
When measuring resistance value or voltage in CAN bus
lines, use a digital multimeter. If not using a digital multim-
eter, the equipments, which are connected through the
CAN communication lines, may be damaged.
(1) Disconnect intermediate connector E-122 and power
control module connector D-134, and measure the voltage
at the female intermediate connector (control wiring
harness side).
(2) Turn the ignition switch to the "ON" position.
CAUTION
Always use the test harness when measuring the voltage
or resistance value at the female connector. If you fail to do
so, connectors may be damaged.
(3) Measure the voltage between intermediate connector
E-122 terminal 20 and body ground.
• The voltage should measure 0.5 volts or more, or 4.5
volts or less.
Q: Does the voltage measure 0.5 volts or more, or 4.5 volts
or less?
YES : Replace the power control module.
NO : Go to Step 19.

STEP 19. Measure the voltage in the CAN_L line. Check at
intermediate connector E-122.
CAUTION
Before checking CAN bus lines and their interconnected
components, "ground" yourself, by touching a metal
object such as an unpainted pipe, this will discharge any
potentially damaging static that may have built up.
CAUTION

lines, use a digital multimeter. If not using a digital multim-
eter, the equipments, which are connected through the

(1) Disconnect intermediate connector E-122 and G and yaw
rate sensor connector E-126, and measure the voltage at
the female intermediate connector (control wiring harness
side).
(2) Turn the ignition switch to the "ON" position.
CAUTION
Always use the test harness when measuring the voltage
or resistance value at the female connector. If you fail to do
so, connectors may be damaged.
(3) Measure the voltage between intermediate connector
E-122 terminal 20 and body ground.
• The voltage should measure 0.5 volts or more, or 4.5
