Self-diagnosis 944
1. General information
1.1 Application
The Systemtester 9288 (BOSCH KTS 301) is a microprocessor-con-
trolled self-diagnosis tester.
All systems which have a diagnosis interface as per ISO Standard can
be tested with this tester. The following tests are possible:
* Reading out the fault memory
* Testing of the actuators
* Testing the circuit inputs
* System adaptation
* Engine-knock detection
* Sensor and status checks, tire-pressure monitoring (RDK)
The Systemtester 9288 is a high-quality pjece of electronic equip-
ment In order to prevent damage to the equipment as a result of
improper use, please read the information in the operating
instructions carefully and comply with it.
In addition. the instructions (specifications) of the vehicle manufac
turer are also to be observed.
If the tester should fail, check the following points before sending it
in for repair:
1. Has the tester been operated incorrectly?
2. Is the battery sufficiently charged?
3. Is the adapter cable OK?
(Please note when checking the adapter cable that a highly sensi-
tive electronic matching circuit is installed in the vicinity of the 19-
pore plug).

Fitted accumulator with NiCd batteries.
The Systemtester 9288 must be switched off
during the initial battery charging process.
Charging time > 8 hours
Discharged upon delivery. Following charge:
Operating time:
4 - 8 hours without scale illumination
