Test 10

Test step 10
Start engine. Check signal of terminal 61-> Specification: Signal present.

For troubleshooting, the status of terminal 61 (present or not present) may also be checked using the Actual values menu.

- Select terminal 61 on the Actual values menu. If the tester displays 'not present" while the engine is running, select the Alarm system and also check the status of terminal 61 in the Input signals menu of the Alarm system. If the signal is present there, the fault is located in the wire between the ABS control unit and the other control unit. Use wiring diagram for troubleshooting. If the terminal 61 signal is not present in the other system either, proceed with the next item.

- Alternator bulb (warning lamp) in instrument cluster faulty. Check bulb (must be on when ignition is switched on).

- Check alternator.
