|---|---|---|---|---|---|
| OK | Problems found | Intervention | |||
| 1 | CHECK THROTTLE POTENTIOMETER WIRING K94 | ||||
| All OK | Remove connector K94 and turn the key to MAR. Connect a digital multimeter (set to read Volts) as follows: – black probe to connector K94 pin 2. – red probe to connector K94 pin 3. ~ 5 Volt should be read |
Go to Step 2 | No voltage is found. The ECU is not powering. | Perform the next check | |
| Perform the next check | Turn the key to STOP and disconnect connectors K94 and M85. Connect a digital multimeter (set to read Ohm) between connector K94 pin 1 and connector M85 pin 35. ~ 0 should be read.Ω |
If > 10 Ω is read, the connection between ECU and potentiometer internal resistance is uncertain. | Restore connection between connector K94 pin 1 and connector M85 pin 35. (wiring diagram: E7040 "ELECTRONIC CLUTCH") |
||
| Perform the next check | Connect a digital multimeter (set to read Ohm) between connector K94 pin 2 and connector M85 pin 5. ~ 0 Ω should be read. |
