Check Signal Lead Resistance to Ground [EG6]
Check Signal Lead Resistance To Ground
- Ignition off.
- Disconnect control module.
- Disconnect combination relay 15-pin connector.
Connect an ohmmeter between test box #1 and:
- #20 (DTC 4-1-1)
- #02 (DTC 4-1-2)
- #38 (DTC 4-1-3)
- #21 (DTC 4-1-4)
- #54 (DTC 4-2-1)
- #36 (DTC 4-2-2)
- #37 (DTC 4-2-3) (TRACS).
Ohmmeter should read infinite resistance.
If reading is OK:
- Check signal lead for short-circuit to supply EG7. Check Signal Lead For Short-Circuit to Supply [EG7]
If reading is incorrect:
- Check lead between hydraulic unit valve block and control module for DTC concerned for short-circuit to ground as per HA3. Short Circuit to Ground [HA3]
- If lead is OK, try another hydraulic unit as per NE. Hydraulic unit, replacement. Service and Repair
