6. Turn the A/C switch to the "ON" position.
7. Measure the voltage between the fan control module-side connector terminals
while the fan is running. The voltage should repeat the values 1) and 2) below.
Standard value:
1.8.2+/-2.6 V
2.Battery positive voltage+/-2.6 V
8. If the voltage does not repeatedly change as indicated, replace the radiator fan

1. Before checks set the vehicle in the following condition:
Engine coolant temperature: 80 - 95°C (176 - 203°F) Lights and all accessories: OFF Transaxle: P range
2. Remove all of the ignition coils and spark plugs.
3. Disconnect the crankshaft position sensor connector.
NOTE: Vehicles for Canada, the headlight, taillight, etc. remain
lit even when the lighting switch is in "OFF" position
but this is no problem for checks.
NOTE: Doing this will prevent the engine control module from
carrying out ignition and fuel injection.

2. Turn the ignition switch to the "ON" position.
3. Check if the DTC is set.
4. Turn the ignition switch to the "LOCK" (OFF) position. Q: Is the check result satisfactory?

YES:
There is an intermittent malfunction such as poor engaged connector
(s) or open circuit (Refer to
HOW TO USE TROUBLESHOOTING/
INSPECTION SERVICE POINTS
).
NO:
Replace the A/C-ECU. On completion, check that the DTC is not
reset.
DTC U1100: POWERTRAIN CONTROL MODULE TIME-OUT (RELATED TO ENGINE) TROUBLE JUDGMENT The A/C-ECU receives engine control system-related signal from the powertrain
control module. If the ECU cannot receive the signal, DTC U1100 will be set. TECHNICAL DESCRIPTION (COMMENT)
CURRENT TROUBLE
Connector(s) or wiring harness in the CAN bus lines between the powertrain
control module and the A/C-ECU, the power supply system to the powertrain
control module, the powertrain control module itself, or the A/C-ECU may be
defective.
PAST TROUBLE
If DTC U1100 is stored as a past trouble, carry out diagnosis with particular
emphasis on wiring and connector(s) in the CAN bus line between the A/C-
ECU
and the powe
rtrain
control m

CAUTION: If DTC U1100 is set in the A/C-ECU, diagnose the
CAN main bus line.
CAUTION: Whenever the ECU is replaced, ensure that the
communication circuit is normal.

powertrain control module. If the connectors and wiring are normal, and
obviously the ECU is the cause of the trouble, replace the ECU. If in doubt, do
not replace the ECU.

communication system)
1.
STEP 1. Using scan tool MB991958, diagnose the CAN bus line.

NOTE: For a past trouble, you cannot find it by the scan tool CAN
bus diagnostics even if there is a failure in CAN bus lines.
In this case, refer to HOW TO USE TROUBLESHOOTING/
INSPECTION SERVICE POINTS
) and check the CAN bus
lines. You can narrow down the possible cause of the
trouble by referring to the DTC, which is set regarding the
CAN communication-linked ECUs (Refer to EXPLANATION
ABOUT THE MUT
-III CAN BUS DIAGNOSIS
).
CAUTION: To prevent damage to scan tool (MUT-III), always
turn the ignition switch to the "LOCK" (OFF)
position before connecting or disconnecting
scan tool (MUT-III).

2. Turn the ignition switch to the "ON" position.
3. Diagnose the CAN bus line.
4. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the CAN bus line found to be normal?

YES:
Go to Step 2.
NO:
Repair the CAN bus lines (Refer to
PRECAUTIONS ON HOW TO
REPAIR THE CAN BUS LINE
).
2.
STEP 2. Using scan tool MB991958 read the powertrain control module
diagnostic trouble code.

Check whether an engine and automatic transaxle DTCs are set or not.
1. Turn the ignition switch to the "ON" position.
2. Check for engine and automatic transaxle DTCs.
3. Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is the check result satisfactory?

YES:
Go to Step 3.
NO:
Diagnose the powertrain control module (Refer to
DIAGNOSTIC
TROUBLE CODE CHART
).
