Relay Circuit Inspection
- Remove the relay box (See Relay Box Removal).
- Check conductivity of the following numbered terminals by connecting the hand tester and one 12 V battery to the relay box as shown (See Relay Box Internal Circuit) in this section).
If the tester does not read as specified, replace the relay box.
Relay Circuit Inspection (with the battery disconnected)
Tester Connection | Tester Reading (Q) | |
Headlight Relay | 1-3 | ∞ |
ECU Main Relay | 7-6 | ∞ |
4-5 | Not ∞* | |
Fuel Pump Relay | 7-8 | ∞ |
9-10 | Not ∞* | |
Starter Circuit Relay | 11-16 | ∞ |
11-12 | ∞ | |
Fan Relay | 17-20 | ∞ |
18-19 | Not ∞* |
*: The actual reading varies with the hand tester used.
Relay Circuit Inspection (with the battery connected)
Battery Connection (+) (—) | Tester Connection | Tester Reading (Ω) | |
ECU Main Relay | 2-11 | 1-3 | 0 |
4-5 | 7-6 | 0 | |
Fuel Pump Relay | 9-10 | 7-8 | 0 |
Fan Relay | 18-19 | 17-20 | 0 |
Battery Connection (+) (-) | Tester Connection DC 25 V Range | Tester Reading (V) | |
Starter Circuit Relay | 16-12 | 11-12 | Battery Voltage |
(+): Apply positive lead.
(-): Apply negative lead.
Diode Circuit Inspection
- Remove the relay box (See Relay Box Removal).
- Check conductivity of the following pairs of terminals (See Relay Box Internal Circuit) in this section).
Diode Circuit Inspection
Tester Connection: 1-11,2-11, 12-13, 12-15, 12-16, 13-14, 13-15
The resistance should be low in one direction and more than ten times as much in the other direction. If any diode shows low or high in both directions, the diode is defective and the relay box must be replaced.
Note: The actual meter reading varies with the meter or tester used and the individual diodes, but generally speaking, the lower reading should be from zero to one half the scale.
