Fig. 10 Transmission Control Module (TCM) for multitronic - J217 -

Component location: The Transmission Control Module (TCM) - J217 - is mounted at the rear of the transmission, directly on the hydraulic unit.

The following components are integrated in the control module.

A - Sender for transmission output RPM - G195 - and Sender 2 for transmission output RPM - G196 -

B - Transmission fluid temperature sensor - G93 -

C - Multi-function transmission range (TR) switch - F125 -

D - Sensor for transmission RPM - G182 -

E - Sender 1 for hydraulic pressure, automatic transmission - G193 -

F - Sender 2 for hydraulic pressure, automatic transmission - G194 -

CAUTION!
Always perform the Adaptation after installing a new Transmission Control Module (TCM) - J217 -.





Fig. 11 Hydraulic Unit

Component location: The hydraulic unit is bolted to the rear of the transmission. The Transmission Control Module (TCM) - J217 - is bolted directly to the hydraulic unit.

A - Wiring connector for Pressure control valve 1 for automatic transmission - N215 -

A - Wiring connector for Pressure control valve 2 for automatic transmission - N216 -

C - Wiring connector for solenoid valve 1 - N88 -

2 - Pressure control valve 2 for automatic transmission - N216 -; transmission ratio solenoid valve

3 - Solenoid valve 1 - N88 -; clutch cooling/safety cutoff

4 - Clutch cooling valve

5 - Minimum pressure valve

6 - Pressure control valve

7 - Clutch control valve

8 - Control pressure valve





Fig. 12 Shift lock solenoid - N110 -

Component location: The shift lock solenoid is located in the shift control mechanism (arrow).





Fig. 13 Data Link Connector (DLC)

Component location: The DLC is located under the knee bolster to the left of the steering wheel.





Fig. 14 Cruise control switch - E45 -

Component location: The cruise control switch is located on the steering column switch.





Fig. 15 Transmission Range (TR) selector lever display - Y6 -

Component location: Integrated in the instrument cluster

Note:
The transmission range selector lever display can only be replaced together with the instrument cluster.





Fig. 16 Relay for power supply terminal 87 and Park/Neutral Position (PNP) relay - J226 -

Component location: On the relay carrier in the E-Box plenum.

3 - Relay for power supply terminal 87

Power supply via terminal 87 is handled through the Motronic ECM power supply relay - J271 -.

4 - Park/Neutral Position (PNP) relay - J226 -





Fig. 17 Brake light switch - F -

Component location: The brake light switch - arrow - is located on the pedal cluster.

Note:
To ensure an adequately tight fit, the switch must only be installed once.





Fig. 18 Kickdown switch - F8 -

Component location:

^ No mechanical switch. A specific value from the Throttle position sensors - G79 -/- G185 - is stored in the Engine Control Module (ECM)
