Checking Wiring
-- Remove the Engine Control Module (ECM) -J623-. Refer to the Repair Information.
-- Using a multimeter, check the Secondary Air Injection (SAI) Pump Relay -J299- socket 4 (relay terminal 85) to the Engine Control Module (ECM) -J623- electrical harness connector T94 for resistance. Refer to Wiring Diagrams for pin locations.
| Secondary Air Injection (SAI) Pump Relay -J299- socket/terminal: | Engine Control Module (ECM) -J623- electrical connector T94 terminal: |
|---|---|
| 4/85 | 94 |
Specified value: 1.5 Ω Max.
If the specified value was Not obtained:
-- Check the wiring for an open circuit, a short circuit to each other, Battery (+) or Ground.
-- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-- If necessary, repair the faulty wiring connection.
If no malfunction is found in the wiring and the relay voltage supply was OK:
-- Replace the Secondary Air Injection (SAI) Pump Relay -J299-.
-- Erase the DTC memory.
-- Perform a road test to verify repair.
