DTC SET CONDITION

｠

DTC B10C0 is set if there is a short circuit in the
interior temperature sensor input circuit.

｠

DTC B10C1 is set if there is a defective connector
connection,  or  if  there  is  an  open  circuit  in  the
harness.

TECHNICAL DESCRIPTION (COMMENT)

Current trouble

｠

The A/C-ECU, the interior temperature sensor, or
connector(s)  or  wiring  between  the  two  may  be
defective.

Past trouble

｠

If DTC B10C0 or B10C1 is stored as a past trouble,
carry  out  diagnosis  with  particular  emphasis  on
wiring and connector(s) between the A/C-ECU and
the  interior  temperature  sensor.  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.

To prevent damage to scan tool MB991958, always turn the
ignition  switch  to  the  "LOCK"  (OFF)  position  before
connecting or disconnecting scan tool MB991958.
Use scan tool MB991958 to diagnose the CAN bus lines.

(1)

Connect scan tool MB991958. Refer to "How to connect the
Scan Tool (M.U.T.-III) P.55B-4."

(2)

Turn the ignition switch to "ON" position.

(3)

Diagnose the CAN bus line.

Q:Is the check result satisfactory?

YES:

 Go to Step 2.

NO:

 Repair the CAN bus lines. Repair the CAN bus lines

(Refer to GROUP 54D, Diagnosis-Can Bus Diagnostic
Chart P.54D-17).

STEP 2. Recheck for diagnostic trouble code.
Recheck if the DTC is set.

(1)

Erase the DTC.

(2)

Turn the ignition switch to "ON" position.

(3)

Check if the DTC is set.

Q:Is the check result satisfactory?

YES:

 It can be assumed that this malfunction is

intermittent. Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points - How to Cope
with Intermittent Malfunctions P.00-15.

NO:

 Go to Step 3.

STEP 3. Check interior temperature sensor connector C-122
and A/C-ECU connector C-109 for loose, corroded or
damaged terminals, or terminals pushed back in the
connector.

Q:Are interior temperature sensor connector C-122 and A/

C-ECU connector C-109 in good condition?

YES:

 Go to Step 4.

AUTO A/C DIAGNOSIS

NO:

 Repair or replace the connector. Refer to GROUP 00E,

Harness Connector Inspection P.00E-2.

STEP 4. Check the wiring harness between A/C-ECU
connector C-109 (terminal 17 and 18) and interior
temperature sensor connector C-122 (terminals 1 and 2).

Q:Is the wiring harness between A/C-ECU connector C-109

(terminal  17  and  18)  and  interior  temperature  sensor

connector C-122 (terminals 1 and 2) in good condition?

YES:

 Go to Step 5.

NO:

 Repair the wiring harness.

STEP 5. Check the interior temperature sensor.

RESISTANCE

TEMPERATURE °C (°F)

(k

)

Measure the resistance between connector terminals 1 and 2
under at least two different temperatures. The resistance values
should generally match those in the graph.

NOTE: 

The temperature at the check should not exceed the

range in the graph.

Q:Is the interior temperature sensor in good condition?

YES:

 Replace the A/C-ECU. Then go to Step 6.

NO:

 Replace the interior temperature sensor. Then go to

Step 6.

STEP 6. Recheck for diagnostic trouble code.
Check again if the DTC is set.

(1)

Connect scan tool MB991958 to the data link connector

(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:

 The procedure is complete.

NO:

 Return to Step 1.
