If specified value is not obtained:

• Replace the valve for camshaft adjustment, see item  11.
• Erase DTC memory of Engine Control Module (ECM), DIAGNOSTIC MODE 4: RESET/ERASE DIAGNOSTIC DATA .
• Generate readiness code, see READINESS CODE, GENERATING .

If specified value is obtained:

• Connect test box to control module wiring harness, see CONNECT TEST BOX FOR WIRING TEST .
• Check wire between test box socket 115 + 2 -pin connector terminal 2 for open circuit according to wiring diagram.

  Wire resistance: max: 1.5 Ω

• Also check wires for short circuit to B+ and Ground (GND).

  Specified value: "INFINITY" Ω

• Check wire between 2 -pin connector terminal 1 and the Fuel Pump (FP) Relay -J17- for open circuit according to wiring diagram.

  Wire resistance: max: 1.5 Ω

If resistances and wires are OK:

• Replace Motronic Engine Control Module (ECM) -J220-, see REPLACING ENGINE CONTROL MODULE (ECM) .
