-
Battery voltage at least 12.5 V.
-
All electrical consumers switched off (radiator fan must NOT run during test).
-
A/C switched off.
-
The ignition switched off.
Procedure
-
Remove the Secondary Air Injection (AIR) Pump Relay -J299-.
Checking voltage
-
Using a Multimeter, check the Secondary Air Injection (AIR) Pump Relay -J299- socket 30 to Ground (GND).
Specified value: battery voltage.
If the specified value was not obtained:
-
Check the wiring connections from the Battery to the Secondary Air Injection (AIR) Pump Relay -J299- socket 30 for an open circuit or a short
circuit.
-
Check the wiring connections for damage, corrosion, lose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If the specified value was obtained:
-
Re-install the Secondary Air Injection (AIR) Pump Relay -J299-.
-
Switch the ignition on.
-
Using a Multimeter, check the Motronic Engine Control Module (ECM) Power Supply Relay J271 socket 85 to the Secondary Air Injection (AIR)
Pump Relay -J299- socket 85 for voltage.
-
Switch the ignition off.
Specified value: battery voltage.
If the specified value was not obtained:
-
Check the wiring connections from the Motronic Engine Control Module (ECM) Power Supply Relay J271 socket 46 to the Secondary Air
Injection (AIR) Pump Relay -J299- socket 85 for an open circuit or a short circuit.
-
Check the wiring connections for damage, corrosion, lose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If the specified value was obtained:
Checking activation
-
Switch the ignition on.
-
Using a Multimeter, check the Secondary Air Injection (AIR) Pump Relay -J299- socket 86 to Ground (GND)
-
Switch the ignition off.
Specified value: battery voltage.
If the specified value was not obtained:
-
Check the wiring connection from the Secondary Air Injection (AIR) Pump Relay -J299- socket 86 to the Motronic Engine Control Module
(ECM) Power Supply Relay J271 socket 87 for an open circuit or a short circuit.
-
Check the wiring connections for damage, corrosion, lose or broken terminals.
-
If necessary, repair the faulty wiring connection.
If the specified value was obtained:
Checking wiring
