Transmission - Control System & Fluids: Maintenance Volvo S60 I

Resetting Transmission Fluid Change Counter

HINT: The transmission control module (TCM) has a counter for the oil quality. The counter counts up if the transmission is exposed to too high a load or an ambient temperature that is too high. If the counter is not reset when the oil is drained or changed, there is a risk that a diagnostic trouble code (DTC) will be stored in faulty circumstances. Therefore it is important that the "Transmission oil change" counter is reset.

Note. This applies only when the transmission fluid is changed and when the fluid is changed when repairs are carried out to the transmission temperature sensor.

1. Ignition on. Reset the counter by clicking on the VCT 2000 symbol.

Resetting Adaptation And the Counter For "Transmission Oil Change"

HINT: The transmission has torque controlled adaptive pressure control. Pressure control means that the transmission regulates the pressure itself during each gear shift. This avoids harsh gear shifting. Each gear shift is evaluated by the control module and stored in the memory. This allows for compensation for wear and tear in the transmission and clutch. It is important that the adaptation in the memory is reset after the transmission has been repaired. This is to ensure normal operation. The oil is replaced during repair; the "Transmission oil change" counter must be reset. If the counter is not reset when the fluid is drained and replaced, there is a risk that a diagnostic trouble code (DTC) will be stored in incorrect circumstances.

Note. This applies only if the transmission or one of the components in the transmission have been replaced.

1. Ignition on. Click on the VCT2000 symbol to reset the adaptation and counter.

Note. Do not damage components and terminals when test measuring. Handle components and terminals carefully.

Check 1

Connect an ohmmeter between terminal #1 and the outer casing of the gear shift solenoid. For resistance values see the table below.

When measuring at temperatures other than +20°C a test measurement must be taken at +20°C. This is to establish if the resistance is correct or not.

Check 2

Connect a temporary voltage supply (+) to gear shift solenoid terminal # 1 and a temporary ground terminal (-) to the gearshift solenoid outer casing. Check the function of the solenoid.

Check 3

Connect a temporary voltage supply (+) to gear shift solenoid terminal #1 and a temporary ground terminal (-) to the gearshift solenoid outer casing. Blow using compressed air according as shown. Check the function of the solenoid.

Connect the breakout box. See Connecting the breakout box

Note. Do not damage components and terminals when test measuring. Handle components and terminals carefully.

Check 1

Connect an ohmmeter to the breakout box between the terminals for the selected solenoid. For resistance values see the table below.
