Test Mode No. 2 (Verifying Operation Of System Components)
This test mode is activated by briefly pressing test button on Volvo diagnostic unit 2 times, causing LED to rapidly flash. ECM will flash a code indicating receipt of a signal from following components with ignition on
- 3-3-2 - TP sensor (throttle moved from or to idle).
- 3-3-3 - TP sensor (throttle moved from or to WOT).
- 1-2-4 - Transmission Control Module (TCM), when gear selector is moved from or to a drive position.
Control unit will flash a code indicating receipt of a signal from following components with engine running
- 1-1-4 - A/C control, when A/C button is depressed or released.
- 1-3-4 - A/C compressor running.
- 1-4-1 - RPM sensor.
- 3-4-2 - Camshaft Position (CMP) sensor.
- 3-4-3 - Vehicle Speed Sensor (VSS).
Note. For test mode No. 3 to operate correctly, 3 injectors must be disconnected. Reconnect injectors after completion of test.
