G-SENSOR
1.
(B24) G-sensor supply circuit open
Turn the ignition off.
Disconnect the Anti-lock Brake module harness connector.
Disconnect the G—sensor harness connector.
NOTE: Check connector - Clean/repair as necessary.
Measure the resistance of the (B24) G-sensor supply circuit from the
G-sensor harness connector to the Anti-lock brake module.
Is the resistance above 5 ohms?
Yes
>> Repair the open (B24) G-sensor supply circuit.
Perform ABS VERIFICATION TEST - VER 1.
No
>> Go to 2
2.
(B24) G-sensor supply circuit shorted to ground
Measure the resistance of the (B24) G-sensor supply circuit from the
G-sensor harness connector to ground.
Is the resistance below 5 ohms?
Yes
>> Repair the (B24) G-sensor supply circuit shorted to
ground.
Perform ABS VERIFICATION TEST - VER 1.
No
>> Go to 3

Perform ABS VERIFICATION TEST - VER 1.
No
>> Go to 5
5.
(B924) G-sensor return circuit open
Measure the resistance of the (B924) G-sensor return circuit from the
G-sensor harness connector to the Anti-lock brake module.
Is the resistance above 5 ohms?
Yes
>> Repair the open (B924) G-sensor return circuit.
Perform ABS VERIFICATION TEST - VER 1.
No
>> Go to 6
