On-vehicle Inspection ON-VEHICLE INSPECTION PROCEDURE
1. REMOVE INTEGRATION RELAY (a) Remove the engine room relay block cover.
| (b) Using a screwdriver, detach the 2 claws and remove the integration relay from the engine room relay block.
HINT: Tape the screwdriver tip before use. | |
(c) Disconnect the 3 connectors. 2. INSPECT INTEGRATION RELAY (IG2)
NOTICE:
- Some relays are built into the integration relay. The integration relay
cannot be disassembled. If there is a malfunction in the circuit of the
integration relay, replace the integration relay.
- The internal circuit of the integration relay is as shown in the
illustration below. Inspect the integration relay using the following
procedures.
 (a) Measure the resistance of the IG2 MAIN fuse.
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance: |
Tester Connection | Condition |
Specified Condition | |
IG2 MAIN fuse | Always |
Below 1 Ω | If the result is not as specified, replace the IG2 MAIN fuse.
| (b) Measure the resistance of the ignition relay No. 2 (IG2).
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance: |
Tester Connection | Condition |
Specified Condition | |
1C-1 - 1B-8 | When battery voltage is not applied to terminals 1B-6 and 1B-7 |
10 kΩ or higher | | When battery voltage is applied to terminals 1B-6 and 1B-7 |
Below 1 Ω | If the result is not as specified, replace the integration relay. |
|
3. INSTALL INTEGRATION RELAY (a) Connect the 3 connectors. (b) Install the integration relay to the engine room relay block.
(c) Install the engine room relay block cover. |
