Mariner 4WD L4-2.5L (2010)
-
Has pinpoint test QA been carried out?
Yes
GO to A3.
No
REFER to Computers and Control Systems Information, Pinpoint Tests, pinpoint test QA to diagnose no communication with the PCM.
-------------------------------------------------
A3 CHECK THE HS-CAN TERMINATION RESISTANCE
-
Ignition OFF.
-
Disconnect: Negative Battery Cable .
-
Measure the resistance between the DLC C251-6, circuit VDB04 (WH/BU), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
-
Is the resistance between 54 and 66 ohms?
Yes
CONNECT the negative battery cable. GO to A6.
No
For non-hybrid, GO to A4.
For hybrid, GO to A5.
-------------------------------------------------
A4 CHECK THE CAN CIRCUITS BETWEEN THE PCM AND THE DLC FOR AN OPEN - NON-HYBRID
-
Measure the resistance between the PCM C175b-59, circuit VDB04 (WH/BU), harness side and the DLC C251-6, circuit VDB04 (WH/BU),
harness side.
-
Measure the resistance between the PCM C175b-58, circuit VDB05 (WH), harness side and the DLC C251-14, circuit VDB05 (WH), harness
side.
-
Are the resistances less than 5 ohms?
Yes
