Test 16 - 20
TEST 16
Left-front sensor cable screen continuity test
Continuity tester between terminals 30 and 1
Ignition OFF
^ Should be no continuity
If incorrect check:
- that sensor is not grounded
- Check sensor cable from sensor to module is not grounded
TEST 17
Check valve block connection
Connect volt meter to terminals 1 and 3
Ignition ON
^ Should be over 10 volts
If no continuity:
- Disconnect the valve block
- Check wiring from pin 30 at relay to terminal 3
- Check wiring from terminal 3 of module to pin of valve block
TEST 18

Ohm-meter connected to terminals 3 and 39 of ABS module
Ignition OFF
^ Correct reading 2 - 5 ohms
If incorrect:
- Disconnect the main valve
- Measure main valve resistance
- Check continuity of wiring from pin 2 of valve to terminal 39 of module connector
- Check pin 1 terminal of valve to module connector terminal 3
TEST 19
Check resistance of RH front inlet valve
Ohm-meter connected to ABS module connector terminals 3 and 38
Ignition OFF
^ Should be 3 - 5 ohms
If incorrect:
- Disconnect valve block
- Measure resistance between valve pins 1 and 7
- Check wiring from ABS module terminal 38 to pin 6 of valve block
TEST 20
Check resistance of rear inlet valve
Ohm-meter connected to ABS module connector terminals 3 and 54
Ignition OFF
^ Should be 3 - 5 ohms
If incorrect:
- Disconnect valve block
- Measure resistance between valve pins 1 and 7
- Check wiring from ABS module terminal 2 to pin 3 of valve block
