C1467: Rear Shock High Side Short to Battery
Diagnostic trouble code C1467 indicates a short circuit to battery voltage (high voltage) on the high side circuit of the rear shock absorber. This code is specific to vehicles equipped with Adaptive Variable Suspension (AVS). The suspension control module detects that the voltage on the rear shock solenoid control circuit exceeds the expected threshold, typically due to a short to battery positive. The system continuously monitors the integrity of the shock actuator circuit to ensure proper control of suspension damping.
1. Commonly Affected Makes
2. Most Common Causes
- Short circuit in the rear shock solenoid wiring to battery power
- Internal short in the rear shock solenoid allowing battery voltage to leak into the control circuit
- Damaged, corroded, or bent pins in the rear shock connector or harness causing a short
- Faulty suspension control module with an internal short in the high-side driver circuit
- Chassis harness damage where the suspension wiring crosses moving parts
3. Symptoms You Will Notice
- Illuminated Check Engine Light or suspension warning light
- Abnormal ride quality, such as excessive stiffness or bouncing from the rear suspension
4. Step-by-Step Diagnosis
Scan for codes and verify C1467 is present; check for related suspension codes.
Visually inspect the rear shock connector and wiring harness for damage, corrosion, or pinched wires.
Disconnect the rear shock solenoid and measure resistance; compare to manufacturer specifications.
Check for battery voltage on the high-side control circuit with the solenoid disconnected; if present, trace the short.
If wiring and solenoid test OK, suspect a faulty suspension control module and perform further module diagnostics.
5. Frequently Asked Questions
Is it safe to drive?▼
Driving is possible but not recommended for extended periods. The suspension may not adjust properly, leading to reduced handling and comfort. Have the issue diagnosed promptly.
How much does it cost to fix?▼
Repair costs typically range from $200 to $800, depending on whether the issue is a simple wiring repair or requires replacing the shock absorber or suspension control module.
