Valve Body Solenoid Valves, Checking
Special tools and workshop equipment required
- Multimeter VAG1526 or Multimeter VAG1715
- Connector test kit VAG1594
- Wiring diagram
Test Prerequisites
- Respective fuses in fuse box (instrument panel, right) must be OK: Refer to SYSTEM WIRING DIAGRAM
- Selector lever must be in P position.
- Ground (GND) connections to transmission must be OK.
- Ignition switched off.
Test Sequence
-- Disconnect 14-pin harness connector -arrow 2- to solenoid valves (Solenoid Valve 1 -N88- to Solenoid Valve 6 -N93-, Solenoid Valve 9 -N282-, Solenoid Valve 10 -N283-).
Checking Resistance
-- Check resistances of solenoid valves at connector to the solenoid valves:
| Component | Connector Terminal | Specified value Ω |
|---|---|---|
| Solenoid Valve 1 -N88- | 1+Ground (GND) transmission | 10.0 to 16.0 |
| Solenoid Valve 2 -N89- | 2+Ground (GND) transmission | 10.0 to 16.0 |
| Solenoid Valve 3 -N90- | 7+8 | 4.0 to 8.0 |
| Solenoid Valve 4 -N91- | 11+12 | 4.0 to 8.0 |
| Solenoid Valve 5 -N92- | 3+4 | 4.0 to 8.0 |
| Solenoid Valve 6 -N93- | 13+14 | 4.0 to 8.0 |
| Solenoid Valve 9 -N282- | 5+6 | 4.0 to 8.0 |
| Solenoid Valve 10 -N283- | 9+10 | 4.0 to 8.0 |
Resistance value is valid at approx. 20 °C. At higher temperatures, resistance value increases.
If one of the specified values is not obtained:
-- Replace the respective solenoid valve.
-- Erase DTC memory of Transmission Control Module (TCM) DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
-- Generate readiness code READINESS CODE .
If specified values are obtained:
-- Check wires according to wiring diagram.
Wiring, Checking
-- Connect test box to control module wiring harness, connect test box for wiring test.
-- Check wires between test box and 14-pin connector to Transmission Control Module (TCM) for open circuit according to wiring diagram.
Wire resistance: max. 1.5Ω
