Starting Test

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

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 appearing in Chart 1 must appear on the engine analyzer screen.

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

Engine 119, 120 CFI/LH-SFI
- Set engine analyzer to"
Engine 119: 4 cylinder position.
Engine 120: 6 cylinder position.
- Set dual ignition adaptor to T1/1 *.
- Ignition: ON.
- Observe and store measured values.
- Set dual ignition adaptor to T1/2 *.
- Observe and store measured values, then
- Printout measured values and compare with specifications.
- Specifications appearing below must appear on the engine analyzer screen.

NOTE: 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.

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