Hydromodulator ABS/4-ETS
For models 463.250/333 produced before 30.09.01.
Details of installation of ABS hydraulic modulator on models 463.250/333 produced up to 30.09.01.
1 - Brake lines; 2 - Connector; 3 - Hydraulic modulator union nuts; 4 - Brake master cylinder union nuts; A7/3 - Hydromodulator ABS/4-ETS
1. On models with the corresponding configuration (code ET2), activate the service mode of the TELE AID emergency call system (see Section Activation/deactivation of the service mode of the TELE AID emergency call system).
2. Turn on the auxiliary battery and connect it to the standard battery, then disconnect the negative cable from the latter.
7 - Auxiliary battery
8 — Positive wire terminal of the module
9 — Terminal of the negative wire of the module
W10 - Battery ground
3. Loosen the union nuts (3 and 4) and disconnect the brake lines (1) - prepare to collect the hydraulic fluid.
4. Disconnect the connector (2) of the hydraulic modulator electrical wiring (A7/3) and remove the latter from the support bracket - if necessary, prepare replacement rubber mounting bushings.
5. Installation is carried out in reverse order - try not to mix up the order of connecting the brake lines.
6. On models with the corresponding configuration (code ET2), deactivate the service mode of the TELE AID system (see Section Activation/deactivation of the service mode of the TELE AID emergency call system).
7. Finally, read the DTC codes and clear the on-board diagnostic system memory using the STAR DIAGNOSIS scanner (6511 1801 00) (See Chapter Engine electrical systems).
