GTI V6-2.8L (BDF) (2002)
Note:
For TDI-PD vehicle with engine codes BEW, BHW.
^
Connect adapter cable (VAG 1598/39-1 and 1598/39-2) to test box (VAG 1598/42).
^
Check wires between VAG 1598 test box and VAS 5258 for open circuit according to wiring diagram.
VAS 5258 probe 3 + Socket 52
VAS 5258 probe 4 + Socket 53
Wire resistance: max. 1.5 ohms
Note:
Continued for all vehicles.
Using probes 3 and 4 of VAS 5258, check wires for short circuit to each other, to vehicle Ground (GND) and to B+.
Specification: infinity ohms
^
Disconnect VAS 5258 from engine harness.
If wiring malfunctions are detected:
^
Locate problem using wiring diagram and repair using VAS 1978 repair kit.
If no wiring malfunctions are detected:
^
Proceed to "-G62- Resistance Measurement".
-G62- Resistance Measurement
Tip:
If -G62- sensor was already replaced in preceding steps, skip this step and continue to second read readiness code step (see below).
Perform resistance measurement on Engine Coolant Temperature (ECT) Sensor -G62-.
^
Connect correct VAS 5258 connector to ECT sensor.
^
Disconnect VAS 5258 from engine harness.
^
Connect Multimeter to VAS 5258 test probes 3 and 4.
Scale A shows resistance values for temperature range 0-50°C (32-122°F).
Scale B shows values for temperature range 50-100°C (122°F-212°F).
Examples:
30°C (86°F) corresponds to a resistance from 1.5 to 2.0 k ohms.
80°C (176°F) corresponds to a resistance from 275 to 375 ohms.
