Checks to be carried out if fault is present
Insufficient battery voltage
| conditions under which the fault appears | checks conditions for checking |
|---|---|
| voltage below 7 V on terminal 1, 29 or 69 of connector 88V.NR of the injection ECU 1320 | engine running at idle, verify: - voltage on terminals 1, 29, 69 of connector 88V.RN - charging circuit |
Battery voltage too high
| conditions under which the fault appears | checks conditions for checking |
|---|---|
| voltage greater than 17,5 V on terminals 1, 29 or 69 of connector 88V.NR of injection ECU 1320 | engine running at idle, verify: - voltage on terminals 1, 29, 69 of connector 88V.RN |
