| Part Number | Tool Name |
|---|---|

| MB991348 | Test Harness Set |
| MB991529 | Diagnostic Code Harness |
| MB991536 | TPS Connector Test Harness |
| MD998706 | Injector Test Set |
| MD998741 | Injector Test Adapter Clip |
| MD998746 | (name not recoverable — see flag below) |
| MD999603 | Injector Test Adapter |

| MD998709 | Hose Adapter, Red (DLI) |
| MB991223 | Multi-Purpose Test Leads, White (LC) |
(verify printed p.122) — part number MD998746’s tool name did not survive OCR (the source line reads as garbled characters “00819 9888” where a name should be). Fuel Injector System (printed p.137) uses MD998746 in a “Clip” role in its test setup diagram, so it is likely a clip/adapter component of the Injector Test Set (MD998706) — but do not publish that as the confirmed tool name without checking a clean scan of printed p.122.
(verify printed p.123) — “Red (DLI)” and “White (LC)” are transcribed literally from the OCR as color/circuit-designator suffixes on the hose adapter and test lead names; the meaning of “DLI” and “LC” is not stated on this page (context elsewhere in the chapter suggests DLI = high-pressure/inlet line, LC = low-pressure/return line, used together for the fuel pressure gauge setup in Fuel Line Pressure Test, but that association is inferred, not printed — confirm before treating as fact).
