Fault symptoms


CHECK ENGINE.


On-Board Diagnostics

Type of diagnosis:


- Once per driving cycle. Interrupted when fault criteria fulfilled or OK reported. Restarts next driving cycle.


Enable criteria:


- Tests 1, 2 and 3: Engine running. A counter accumulates a value for each second that passes since the engine was started. With the accelerator pedal depressed, the value is 1 and with the accelerator pedal released, the value is 0.5. Starting temperatures for intake air and coolant have been registered and the lowest of them has been selected.


Fault criteria:


- Test 1: When the temperature value is below -7°C, the counter reaches 600 before closed loop starts.

- Test 2: When the temperature value is between -7°C and 10°C, the counter reaches 300 before closed loop starts.

- Test 3: When the temperature value exceeds 10°C, the counter reaches 120 before closed loop starts.


Dependents:


- None.


System reaction to a fault:


- None.


OK report:


- Closed loop activated before the fault criteria are fulfilled for any of the tests.


Fault handling: (See section Fault handling III, other emission-related components and functions for more information.)


- Type III.

Checking the wiring

Jiggle the wiring harness at several points and in different directions to detect intermittent breaks and short circuits. Observe the multimeter, diagnostic tool or test lamp during the check.
