If Injection Pump Did Operate and Run
-- Reinstall the Secondary Air Injection (AIR) Pump Relay - J299 -. Refer to the appropriate service information.
-- Switch the ignition ON.
-- Using a test light or Multimeter, check the Secondary Air Injection (AIR) Pump Relay - J299- socket terminal 2/85 and 3/30 to Ground (GND).
Specified value: Battery voltage.
-- Switch the ignition OFF.
If the specified value was Not obtained:
-- Check the wiring connection from the Secondary Air Injection Pump Relay - J299- terminals to Fuses for an open or short circuit (Refer to applicable wiring diagram for fuse positions).
-- Check the wiring connections for damage, corrosion, loose or broken terminals.
-- If necessary, repair the faulty wiring connection.
-- Repair the circuit and replace any open fuses.
-- Go to Final procedures
If the specified value was obtained:
Checking Ground (GND) activation
-- Remove the Engine Control Module (ECM) - J623 -. Refer to the appropriate service information.
-- Using a Multimeter, check the Secondary Air Injection Pump Relay - J299- socket terminal 1/86 to the Engine Control Module (ECM) - J623- electrical harness connector T94 for resistance.
| Secondary Air Injection Pump Relay -J299- socket terminal: | Engine Control Module (ECM) -J623- electrical connector T94 terminal: |
|---|---|
| 1/86 | 7 |
Specified value: 1.5 Ω Max.
If the specified value was Not obtained:
-- Check the wiring for a short circuit to Battery voltage, or an open circuit.
-- Check the electrical harness connector for damage, corrosion, loose or broken terminals.
-- If necessary, repair the faulty wiring connection.
-- Go to Final procedures
If the specified value was obtained:
-- Exchange the Secondary Air Injection (AIR) Pump Relay - J299- with the Engine Control Module Power Supply Relay -J271- located Near to it. Refer to Wiring Diagrams.
-- Attempt to start the engine.
Specified value: Engine Started.
-- Switch the ignition OFF.
If the specified value was obtained:
-- Replace the Engine Control Module (ECM) - J623-. Refer to the appropriate service information.
If the specified value was Not obtained:
-- Replace the Secondary Air Injection (AIR) Pump Relay - J299-. Refer to the appropriate service information.
Final procedures
-- Reinstall the engine covers, if necessary. Refer to the appropriate service information.
-- After the repair work, the following work steps must be performed in the following sequence:
- Check the DTC memory. Refer to DIAGNOSTIC MODE 03 - READ DTC MEMORY .
- If necessary, erase the DTC memory. Refer to DIAGNOSTIC MODE 04 - ERASE DTC MEMORY .
- If the DTC memory was erased, generate readiness code. Refer to READINESS CODE .
