PROCEDURE
1. | CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P26CE37) |
(a) Connect the Techstream to the DLC3.
(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Read the DTCs.
Powertrain > Engine > Trouble Codes Result | Proceed to |
---|---|
DTC P26CE37 is output | A |
DTC P26CE37 and other DTCs are output | B |
DTC P26CE37 and P26CB71 are output | C |
HINT:
B | GO TO DTC CHART |
C | GO TO DTC P26CB71 |
|
2. | CHECK ENGINE COOLANT LEVEL IN RESERVOIR TANK |
(a) Check that the engine coolant level is between the FULL and LOW lines.
Click here
Result | Proceed to |
---|---|
Engine coolant level is above the LOW line | A |
Engine coolant level is below the LOW line | B |
A | GO TO STEP 6 |
|
3. | CHECK FOR ENGINE COOLANT LEAKS |
(a) Check the areas around the engine and heater for engine coolant leaks.
Click here
HINT:
If the engine oil is cloudy during the engine oil level gauge check, it means that engine coolant has entered the engine lubrication system.
OK:
No leaks.
NG | GO TO STEP 5 |
|
4. | ADD ENGINE COOLANT |
(a) Fill the reservoir tank up to the FULL line with engine coolant.
NOTICE:
Make sure not to add engine coolant when the engine is hot.
NEXT | GO TO STEP 6 |
5. | REPAIR OR REPLACE MALFUNCTIONING PARTS, COMPONENT AND AREA |
(a) Repair any engine coolant leaks.
HINT:
Add engine coolant and perform air bleeding after repair.
|
6. | BLEED ENGINE COOLANT |
(a) Bleed air from the cooling system.

(b) Turn the power switch on (IG).
(c) Turn the Techstream on.
(d) Clear the DTCs.
Powertrain > Engine > Clear DTCs(e) Turn the power switch off and wait for at least 30 seconds.
|
8. | CHECK WHETHER DTC OUTPUT RECURS (DTC P26CE37) |
(a) Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern.
