TEST POINT 53
No Current In Tank Servo motor Despite Relay Actuation

Fault Code 58
This fault is stored in the following cases:
- Short circuit to ground or open circuit between plug II on control module pin 5 or 10, and tank cap actuator
- Pin 1 or 2 or faulty shift elements for tank cap.

Procedure

In the menu item Drive Links, select "Tank locking" and carry out the drive link test. If the shift element for the tank cap does not react:

1. Pull plugs I and II off the alarm system control module

Ohmmeter at alarm system control module plug II, pin 1 and ground

Display: < 5 ohms

2. Pull plug off shift element for tank cap.

- Voltmeter at alarm system control module plug II, pin 10 and ground

Display: 0 Volts

- Voltmeter at alarm system control module plug II, pin 5 and ground

Display: 0 Volts

- Ohmmeter on alarm system control module plug I, pin 10 and plug on shift element for tank cap pin 1

Display: < 5 ohms

- Ohmmeter at alarm system control module plug I, pin 10 and ground

Display: infinity

- Ohmmeter on alarm system control module plug I, pin 5 and plug on shift element for tank cap pin 2

Display: < 5 ohms

- Ohmmeter at alarm system control module plug I, pin 5 and ground

Display: infinity

If no faults are detected in the wire, replace the shift element for the tank cap.
