Instrument Cluster Module

Installation Position Of The Instrument cluster Module

Operation of the Instrument Cluster Module
- Activation of the overdrive control light
- Triggering the low coolant level indicator lamp
- Activation of the selector lever locking device solenoid
- Triggering the park position warning chime

Overdrive Control Light
The overdrive indicator lamp is triggered if the instrument cluster module receives a signal which is output by the Powertrain Control Module (PCM). This is the case when the driver locks into fourth gear by activating the overdrive switch. The indicator lamp is dimmed if the light switch is switched on.

Low Coolant Level Indicator Lamp
The low coolant level indicator lamp is triggered for 5 seconds after the ignition is switched on, to test the lamp. This test is always carried out, independently of the coolant level. If the low coolant level switch is already open when the ignition is switched on, i.e. the coolant level is too low, the indicator lamp remains on. To equalize possible hunting movements during operation, the indicator lamp is triggered with a time delay if low coolant level is established. This is the case if the switch is open for a total of 60 seconds. The indicator lamp goes out if the ignition is switched off or if the switch is closed for a total of 60 seconds longer than it is open.

Selector Lever Locking Device Solenoid
The selector lever locking device solenoid is unlocked when the ignition is switched on if a signal which is output by the brake-light switch when it is actuated is received. At the same time, the selector lever locking device switch must be pressed. A drive position can only be selected when the selector lever locking device solenoid is unlocked.

Park Position Warning Chime
The instrument cluster module outputs a signal to the CTM if the selector lever locking device switch reports that the selector lever is not in park position. If a contact in the ignition lock (in the case that the ignition key is in) or the instrument cluster module outputs this signal, and if the driver's door is open, the warning chime in the CTM sounds until the key is removed and the selector lever is put into park position.
