1. Turn OFF the ignition.
2. Disconnect the engine control module (ECM)
harness connector.
3. Turn ON the ignition, with the engine OFF.
4. Connect a 3-amp fused jumper wire between the
glow indicator lamp control circuit of the ECM
harness connector (pin 40 of C-56 connector)
and a known good ground.
Does the glow indicator lamp illuminate?
Go to Step 10
Go to Step 7

1. Turn OFF the ignition.
2. Remove the instrument panel (IP) cluster.
3. Connect a test lamp between the voltage feed
circuit of the glow indicator lamp (pin 8 of B-24
connector) and a known good ground.
4. Turn ON the ignition, with the engine OFF.
Does the test lamp illuminate?

Go to Step 11
8
1. Turn OFF the ignition.
2. Reconnect the ECM harness connector.
3. Connect a test lamp between the voltage feed
circuit and control circuit of the glow indicator
lamp (pin 8 of B-24 connector and pin 35 of B-23
connector).
4. Turn ON the ignition, with the engine OFF.
5. Perform the Glow Indicator test with the scan
tool.
6. Command the Glow Indicator ON with the scan
tool.
Does the test lamp turn ON when commanded ON
with the scan tool?
Go to Step 13
Go to Step 12
9
1. Test the control circuit of the glow indicator lamp
between the ECM (pin 40 of C-56 connector) and
the IP cluster (pin 35 of B-23 connector) for a
short to ground.
2. Repair the circuit(s) as necessary.
Did you find and correct the condition?

Go to Step 16
10
1. Turn OFF the ignition.
2. Disconnect the ECM harness connector.
3. Inspect for an intermittent and for a poor
connection on the glow indicator lamp control
circuit at the harness connector of the ECM (pin
40 of C-56 connector).
4. Repair the connection(s) as necessary.
Did you find and correct the condition?
Go to Step 17
Go to Step 16
11
Repair the open circuit or high resistance on the
voltage feed circuit of the glow indicator lamp
between the IP cluster (pin 8 of B-24 connector) and
Meter (10A) fuse (C-14).
Did you complete the repair?
Go to Step 17
12
1. Repair the open circuit or high resistance on the
control circuit of the glow indicator lamp between
the ECM (pin 40 of C-56 connector) and the IP
cluster (pin 35 of B-23 connector).
2. Repair the circuit(s) as necessary.
