PROCEDURE
1. INSPECT PTC HEATER RELAY(PTC HTR NO. 1, NO. 3)
(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 between terminals 1 and 2 | 10 kΩ or higher | 3 - 5 | Auxiliary battery voltage is applied between terminals 1 and 2 | Below 1 Ω | -
If the result is not as specified, replace the PTC heater relay (PTC HTR NO. 1, NO. 3).
| | *a | Component without harness connected (PTC Heater Relay) | | |
2. INSPECT PTC HEATER RELAY(PTC HTR NO. 2)
