Test No. 5
- Disconnect Hydraulic Control Unit (HCU) connector. Using a voltmeter, check for voltage between ground and HCU wiring harness connector terminal No. 8. See Fig 1
. If battery voltage exists, replace HCU. If battery voltage does not exist, go to next step.
- Inspect connectors between HCU and instrument cluster. Clean or repair as necessary. Verify if original problem still exists. If problem still exists, check Green/Red wire between HCU and instrument cluster. Repair as necessary.
