(B136) No. 6 — Chassis ground:
(B136) No. 5 — Chassis ground:
(B136) No. 4 — Chassis ground:
(B136) No. 3 — Chassis ground:Is the resistance less than 1
Ω?Repair ground
short circuit in har-
ness between
ECM and fuel
injector connector.Go to step 5.
5 CHECK EACH FUEL INJECTOR.
1) Turn the ignition switch to OFF.
2) Measure the resistance between each fuel
injector terminals.
Te r m i n a l s
No. 1 — No. 2:Is the resistance 5 — 20 Ω? Go to step 6.Replace the faulty
fuel injector.
6 CHECK POOR CONTACT.
Check poor contact in ECM connector.Is there poor contact in ECM
connector?Repair the poor
contact in ECM
connector.Inspection using
