Signal Too High. Permanent Fault
Signal too high. Permanent fault
Checking wiring and components
Check injector resistance between terminals 1 and 2.
Check cable between injector terminal 2 and control module:
- #A16 (#A16) (ECM 2310)
- #A34 (#A34) (ECM 2320)
- #A15 (#A15) (ECM 2330)
- #A33 (#A33) (ECM 2340)
- #A14 (#A14) (ECM 2350)
for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Hint: Use an electrician's screwdriver with at least a 3 W bulb to determine whether the cable is short-circuited to supply voltage.
Remedy as necessary.
