| CHECK HARNESS BETWEEN ECM AND SECONDARY AIR PUMP RELAY. |
|
Measure the resistance between ECM and chassis ground. Connector & terminal (B136) No. 8 — Chassis ground: |
| QUESTION | |
|
Is the resistance 1 MΩ or more? | |
| Yes | No |
|
Even if the malfunction indicator light illuminates, the circuit has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again. NOTE: In this case, temporary poor contact of connector may be the cause. |
