Checking wiring and sensors
Checking the power supply
Check the power supply cable between the control module
- terminal #36 (#A36) (left rear)
- terminal #43 (#A43) (right rear).
and terminal #1 on the relevant sensor. Check for an open-circuit. Check for a short-circuit to ground. Check for a short-circuit to supply voltage.
HINT: With the ignition on, the voltage should be approximately 1 V under Ubat measured at the ground terminal.
Checking the signal cable
Check the power supply cable between the control module
- terminal #37 (#A37) (left rear)
- terminal #42 (#A42) (right rear).
and terminal #2 on the relevant sensor. Check for an open-circuit. Check for a short-circuit to ground. Check for a short-circuit to supply voltage.
Checking the function of the sensor
Check the sensor. Ensure that the breakout box is connected, the sensor is connected and the ignition is on. Measure the signal from the sensor. Connect a voltmeter between:
- terminals #36 (#A36) and #37 (#A37) (left front)
- terminals #43 (#A43) and #42 (#A42) (right front).
on the breakout box. The voltage should vary by approximately 1 V when the pulse wheel is rotating. Replace the wheel sensor if the voltage is faulty.
Remedy as necessary.
