Measure the resistance between ECM connector and chassis ground.

Connector & terminal

(B135) No. 90 — Chassis ground:

(B135) No. 60 — Chassis ground:

QUESTION

Is the resistance 1 MΩ or more?

Yes No

In this case, repair or replace the following item:

• Short circuit to ground in harness between ECM connector and glow relay connector

• Blown out of fuse (relay block)
