ENGINE 111.979 in MODEL 901, 902, 903, 904
| PEC fuel injection and ignition system diagnosis previous knowledge | ||
| Battery voltage 11 up to 14 V | ||
| HHT connected to diagnostic socket | ||
| Remove left headlamp unit | ||
| Connect test wiring harness with socket box at ME-SFI control unit according to connection diagram. | Do not unplug control unit sockets unless ignition switched off | |
| PMS system complete (all connectors connected) | ||
| Cables, connectors and plug connectors are covered by the test with the HHT and may have to once again tested separately, if a fault is displayed, for open circuit, good contact and correct connection on the basis of the valid wiring diagram. | ||
| Use of testers Clip on and unclip secondary pickup at corresponding ignition line and trigger clamp at cylinder 1 only when engine is stationary and ignition OFF. | ||
