Mercedes Benz Truck GLK 350 Technical Problem # S-07_04-88 Date: 110701 Cooling System - MIL ON/DTC P2060 Diagnosis Date: July 2011

Mercedes Benz Truck GLK 350 Technical Problem # S-07_04-88 Date: 110701
Cooling System - MIL ON/DTC P2060 Diagnosis
Date: July 2011
Order No.: S-B-07.04/88
Supersedes:
Group: 07
SUBJECT: All Passenger and Light Truck Models Equipped with Engine M272 and PremAir Sensor B11/15
Check Engine Light On (DTC 2060) -> PremAir Sensor B11/15 - Diagnosis
Note:
The information provided below only pertains to DTC's 2060 or P256809 regardless of code description.
In cases of a customer complaint of a CEL and either DTC 2060 or P256809 are current and or stored in the ME ECU, please perform the following
diagnosis and provide the following information to the Dealer Technical Support (DTS) group in the form of an on-line DTS case. Once all required
information has been entered and attached to the case, then call the DTS hotline for further work instructions.
1. Print-out and or save a copy of the initial short test, fault code freeze frame data via the ME DTC menu, and a ME ECU log.
2. Insure that the vehicle has not been in an accident.
3. Insure that the correct radiator is installed (PZEV radiator = black catalytic coating).

4. Insure the radiator is not damaged or obstructed.
5. Perform a function test of the premair sensor (code must be present). If the test does not pass, then erase the code and perform a function test via
the guided test menu. In the event the function test is performed on a hybrid model, then monitor if the function test is inconclusive (i.e. there are no
test result data at the conclusion of the test [numerical or graph]). Print and or save both before and after test results (code/no code).
Note:
If there is no guided test menu, then contact the SDS helpdesk for assistance.
6. Check glycol/water mixture.
7. Check the ground circuit of the premair sensor via a DVOM first and then visually (ground stud must be clean).
8. Check pin bushing tension of premair sensor connector.
9. Check premair sensor installation as outlined in S-B-07.04/87.
Note:
If the premair sensor detaches from the radiator without breaking and or damaging the sensor tip, then the sensor is not properly installed. If the
sensor tip does break off, then the sensor was properly installed.
The on-line DTS case notes should include the following information:
^ Repair attempts to date = ?
^ Internal ME software version currently installed = VC?
^ Accident damage related = yes/no
^ Correct radiator installed = yes/no
^ Obstructions of radiator noted = yes/no
^ PremAir function test result with code present = pass/failed
^ PremAir function test result with code erased = pass/failed
^ Resistance test of premair sensor ground circuit = ? ohms
^ PremAir sensor ground stud condition = clean/not clean
^ Pin bushing tension of premair sensor connector = loose/tight
^ Coolant/Antifreeze - water ratio measured at = ? degrees
^ PremAir sensor properly bonded in place = yes/no
The following SDS data should be attached to the on-line DTS case:
^ Initial short test
^ Freeze frame data via the DTC fault menu
^ ME ECU log
^ Premair function test result (numerical data and graph)
