1. Turn OFF the ignition.
2. Connect a test lamp between the control circuit
of the glow relay (pin 3 of X-5 connector) and
battery voltage.
3. Turn ON the ignition, with the engine OFF.
Does the test lamp continuously illuminate (the test
lamp blinks then goes out normally if the engine
coolant temperature lower than 30°C [86°F])?

Repair the voltage feed circuit between the ECM
(10A) fuse (EB-4) and the glow relay (pin 2 of X-5
connector) for an open circuit or high resistance.
Did you complete the repair?
Go to Step 16
10
1. Test the control circuit of the glow relay between
the engine control module (ECM) (pin 16 of C-57
connector) and the glow relay (pin 3 of X-5
connector) for a short to ground.
2. Repair the circuit(s) as necessary.
Did you find and correct the condition?

13
1. Turn OFF the ignition.
2. Disconnect the ECM harness connector.
3. Inspect for an intermittent and for a poor
connection on the glow relay control circuit at the
harness connector of the ECM (pin 16 of C-57
connector).
4. Repair the connection(s) as necessary.
Did you find and correct the condition?
