Cut the

are disconnected.

Use the multimeter to check the bus cables. The con-

ductors in the bus cables should not be in contact with

each other.

Disconnect a bus cable at each end and measure the

resistance between the pins to check this. The multi-

meter should show infinite resistance between each

pin. If the resistance is less than infinite, there is a fault.

If there is an open circuit, the resistance is infinite, and

if there is a short circuit, it is close to zero. The resist-

ance values given in the workshop manual are approx-

imate, and should be regarded as guidelines.

NOTICE! When resistance measurement is done, the

engine should be stopped and system voltage should

be cut off with the main switch.

All resistance measurement is done at +20 °C (68 °F)

and with a cold engine.
