| STEP | CHECK TO BE PERFORMED | RESOLUTION IF THE CHECK IS NOT OK |
|---|
| 1 | Checking Cruise Control command statusConnect the Examiner tester to the engine control unit in parameter mode and check that the cruise control parameter status changes:- ON command- OFF command | Move on to Step 5 |
| 2 | Checking Cruise Control command statusConnect the Examiner tester to the engine control unit in parameter mode and check that the cruise control parameter status changes:- Set + command | Move on to Step 6 |
| 3 | Checking Cruise Control command statusConnect the Examiner tester to the engine control unit in parameter mode and check that the cruise control parameter status changes:- Set - command | Move on to Step 7 |
| 4 | Checking Cruise Control command statusConnect the Examiner tester to the engine control unit in parameter mode and check that the cruise control parameter status changes:- Recall commandThe test can be considered over | Move on to Step 8 |
| 5 | Check resistanceDisconnect the wiring side connector from the steering wheel stalk unit Cruise control stalk- Place the Cruise Control control in "ON" position- Select the Ohmmeter function on the Examiner- Connect the probes between pins A8 and A10 of the Cruise Control stalk connector and ensure a resistance reading of approximately 2480 Ohm +/- 20 % is present at 20°C | Replace the Cruise Control stalk assembly Op. 5550A10 STALK UNIT ASSEMBLY - R+R |
| 6 | Check resistanceDisconnect the wiring side connector from the steering wheel stalk unit Cruise control stalk- Place the Cruise Control control in "SET+" position- Select the Ohmmeter function on the Examiner- Connect the probes between pins A8 and A10 of the Cruise Control stalk connector and ensure a resistance reading of approximately 345 Ohm +/- 20 % is present at 20°C | Replace the Cruise Control stalk assembly Op. 5550A10 STALK UNIT ASSEMBLY - R+R |
| 7 | Check resistanceDisconnect the wiring side connector from the steering wheel stalk unit Cruise control stalk- Place the Cruise Control control in "SET-" position- Select the Ohmmeter function on the Examiner- Connect the probes between pins A8 and A10 of the Cruise Control stalk connector and ensure a resistance reading of approximately 740 Ohm +/- 20 % is present at 20°C | Replace the Cruise Control stalk assembly Op. 5550A10 STALK UNIT ASSEMBLY - R+R |
| 8 | Check resistanceDisconnect the wiring side connector from the steering wheel stalk unit Cruise control stalk- Place the Cruise Control control in "RECALL" position- Select the Ohmmeter function on the Examiner- Connect the probes between pins A8 and A10 of the Cruise Control stalk connector and ensure a resistance reading of approximately 132 Ohm +/- 20 % is present at 20°C | Replace the Cruise Control stalk assembly Op. 5550A10 STALK UNIT ASSEMBLY - R+R |
