Starting Test

Diagnosis - Starting Test

Ignition: ON
- Starting test should only be performed if engine does not run.
- Test and adjustment dat. Test and Adjustment Data [Specifications]

a) Engine 102, 103, 116, 117 CFI, 104 CFI/LH-SFI

Test sequence:
- Connect engine analyzer.
- Ignition: ON.
- Observe measured values and store or print out.
- Specifications shown below must appear on the engine analyzer screen.


NOTE: The starting test on engines 104, 111 HFM-SFI is only possible with the oscilloscope.

b) Engine 119,120 CFI/LH-SFI
- Set engine analyzer to:
- 4 cylinder position for engine 119;
- 6 cylinder position for engine 120.
- Set dual ignition adaptor to T1/1 1).
- Ignition: ON.
- Observe and store measured values.
- Set dual ignition adaptor to T1/2 1).
- Observe and store measured values, then
- Print out measured values and compared with specifications.
- Specifications shown below must appear on the engine analyzer screen.

WARNING:
On engine 120, the diagnostic socket adapter must in addition be set for the appropriate ignition circuit.
Example: Dual ignition adaptor T1/1
When checking ignition timing on circuit T1/2 the trigger clamp must be attached to the ignition cable for the no. 12 cylinder.

1) The measurements between T1/1 and T1/2 must be carried out separately.
