PROCEDURE
1. INSPECT IGNITION CONTROL RELAY (IGCT)
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance: | Tester Connection | Condition | Specified Condition | | 3 - 5 | Auxiliary battery voltage is not applied across terminals 1 and 2 | 10 kΩ or higher | | 3 - 5 | Auxiliary battery voltage is applied across terminals 1 and 2 | Below 1 Ω | If the result is not as specified, replace the ignition control relay. | | | *1 | Ignition Control Relay | | |
2. INSPECT HYBRID WATER PUMP RELAY (INV W/PMP)
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance: | Tester Connection | Condition | Specified Condition | | 3 - 5 | Auxiliary battery voltage is not applied across terminals 1 and 2 | 10 kΩ or higher | | 3 - 5 | Auxiliary battery voltage is applied across terminals 1 and 2 | Below 1 Ω | If the result is not as specified, replace the hybrid water pump relay. | | | *1 | Hybrid Water Pump Relay | | |
