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.

Component	Note	Resistance (Ω)
Gear shift solenoid S1, S2	Resistance between the solenoid pins and the solenoid casing/transmission housing	+20°C= 11-16 Ω

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.
